Verse-by-Verse Commentary
The Book of Genesis
Chapter 4: Cain and Abel
Outside Eden, the fall bears its first bitter fruit. Two brothers bring offerings to the LORD; one is received and one is not, and envy hardens into the first murder. God warns Cain that sin lies at the door, confronts him over his brother's blood, and yet marks him with mercy even in judgment. The chapter traces Cain's line as it builds cities and boasts of violence, then closes with hope: Seth is born, and men begin to call on the name of the LORD.
About This Commentary
This is a verse-by-verse study of Genesis chapter 4. For each section you will find the KJV text, the Hebrew words that sharpen the meaning, plain explanation, and a Gospel Focus where the text touches the one God and His plan of salvation. Chapter 4 shows sin spreading from the garden into the family and the world, and God's grace still at work. Every Scripture quotation is from the King James Version.
Setting the Stage
Two Offerings
Cain the farmer and Abel the shepherd both bring offerings to the LORD. God receives Abel and his offering but not Cain and his, and the difference, Scripture shows, lay in faith and in the heart.
Sin at the Door
Before any blood is shed, God warns Cain: sin is crouching at the door like a beast, desiring him, and he must rule over it. The first murder was preceded by a rejected warning.
The First Murder
Cain rises against Abel his brother and kills him, and the voice of Abel's blood cries out to God from the ground. Sin has moved from eating forbidden fruit to shedding a brother's blood in one generation.
Seth, and the Name
The chapter ends not with Cain's proud line but with Seth's birth and a quiet revival: "then began men to call upon the name of the LORD." The promised line of the woman's Seed continues.
Cain and Abel Are Born (Genesis 4:1-2)
Life goes on outside Eden. Eve bears two sons, and with the first birth she names the LORD as the giver.
A Man from the LORD
"And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD. And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground."
Hebrew Study
"Cain," Qayin (קַיִן). The name Eve gives her firstborn is drawn straight out of her own cry at his birth. Some hear in her words the hope that this child might be the promised Seed of Genesis 3:15. If so, the hope was sadly misplaced; the deliverer would come, but not yet, and not through Cain.
"gotten," qanah (קָנָה). Eve's words are a wordplay: she named him Cain because she had "gotten," that is, acquired (qanah), a man from the LORD. Name and verb sound alike, so that every time the boy is called, his mother's claim is heard again.
"Abel," Hevel (הֶבֶל). The name means breath or vapor, the same word Ecclesiastes uses for the fleeting brevity of life. His name would prove tragically fitting: his life, though righteous, was cut short like a breath.
Explanation
Verse 1 records the first human birth. Even fallen and exiled, Eve confesses that life comes "from the LORD"; childbearing, though now marked by sorrow (3:16), is still God's gift. Verse 2 introduces the second son and the two callings: "Abel was a keeper of sheep, but Cain was a tiller of the ground." Both are honest vocations; the shepherd and the farmer both work the world God made. Nothing in their work decides what follows. The difference between these brothers will not be their occupation but their hearts before God.
Gospel Focus
When Eve bore her firstborn she cried, "I have gotten a man from the LORD," perhaps hoping this was the promised seed who would bruise the serpent's head. But the Deliverer would come in God's own time, and Cain would prove to be one "who was of that wicked one" (1 John 3:12). Still the promise held: through this family, despite murder and sin, God would preserve the line that led at last to Jesus Christ, the true Seed. And Abel, "a keeper of sheep," is the first of a long line of shepherds who point to the Good Shepherd; more than that, his righteous blood, shed by the hand of a brother, foreshadows the greater blood of Christ, which "speaketh better things than that of Abel" (Hebrews 12:24), crying not for vengeance but for mercy.
The LORD Had Respect unto Abel's Offering (Genesis 4:3-7)
Both brothers come to worship, but God receives one offering and not the other, and His warning to angry Cain is one of the most searching passages on sin in all of Scripture.
Sin Lies at the Door
"And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen? If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him."
Hebrew Study
"an offering," minchah (מִנְחָה), a gift, tribute. A gift or tribute brought to a superior. Both brothers bring one -- Cain of the fruit of the ground, Abel of the firstlings of his flock and of the fat thereof -- so the difference between them does not lie in the word used for what they carried.
"had respect," vayyisha (וַיִּשַׁע), looked with favour. God accepts Abel's offering of the firstlings but not Cain's. The word is one of favourable regard: the LORD looked with favour on the one worshipper and his gift, and did not so look on the other.
"very wroth," vayyichar me'od (וַיִּחַר מְאֹד), burned with anger. The Hebrew pictures anger as a heat kindled inside the man, and Cain's burns hot; his countenance falls with it. Yet God does not strike him down for it -- He comes to the angry man with a question: "Why art thou wroth? and why is thy countenance fallen?"
"sin lieth at the door," chattat rovetz (חַטָּאת רֹבֵץ), sin croucheth like a beast. God warns Cain that sin crouches like a predator at the door, waiting to master him unless he masters it. The picture is of an animal gathered and still, ready to spring on the man who will not deal with it.
"rule over him," timshol-bo (תִּמְשָׁל־בּוֹ). This is not a fresh phrase; it is the identical construction God spoke to Eve just one chapter earlier -- "thy desire shall be to thy husband, and he shall rule (yimshol) over thee" (3:16). Sin is now pictured with a wife's "desire" for Cain, and Cain is told to do to sin what the husband does in that verse: rule over it. The same words that once described a marriage now describe a battle -- mastery is still the calling, only the enemy has changed.
Explanation
Verses 3 and 4 set the two offerings side by side. Cain brings "of the fruit of the ground an offering"; Abel brings "of the firstlings of his flock and of the fat thereof," the first and the best, a life laid down. Verses 4 and 5 give heaven's verdict: "the LORD had respect unto Abel and to his offering," but "unto Cain and to his offering he had not respect." Notice the order in both cases: God looked at the man before the gift. Hebrews supplies the key: "By faith Abel offered unto God a more excellent sacrifice than Cain" (Hebrews 11:4). Abel came in faith, bringing a firstling from the flock; Cain came with produce but without the faith and heart God receives. Cain's response to correction is not repentance but anger: "Cain was very wroth, and his countenance fell."
Verses 6 and 7 are God's mercy to the angry man. The LORD comes to Cain with questions, as He came to Adam, inviting him back: "If thou doest well, shalt thou not be accepted?" The door to acceptance stood open. Then the warning: "if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him." Sin is pictured as a beast crouching at the door, hungry for him. The words echo 3:16 deliberately: as the woman's "desire" was to her husband, sin's desire is toward Cain, but he is charged to master it. God treats Cain as responsible, warned, and able by obedience to turn; the murder that follows was not fate.
Gospel Focus
Here at the first act of worship after Eden, the Bible teaches that God does not receive every offering. Worship is not accepted because it is sincere effort or costly produce; it is accepted when it comes God's way, in faith, from a right heart. Abel's firstborn lamb stands in the long line that runs from the coats of skin in Eden through the Passover to "the Lamb of God, which taketh away the sin of the world" (John 1:29). And God's warning to Cain still stands over every tempted soul: sin crouches at the door, but it does not have to come in. By the grace and Spirit of God, "thou shalt rule over him," for "sin shall not have dominion over you" (Romans 6:14). Anger nursed becomes murder; the time to master sin is at the door, not after it has entered.
Your Brother's Blood Cries Out (Genesis 4:8-10)
The warning is refused, and envy does its full work. God comes again with a question, and again hears evasion instead of confession.
Am I My Brother's Keeper?
"And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him. And the LORD said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother's keeper? And he said, What hast thou done? the voice of thy brother's blood crieth unto me from the ground."
Hebrew Study
"rose up against," vayyaqam el (וַיָּקָם אֶל). From qum, "to rise, to stand up," the same verb used throughout Genesis for deliberate, purposeful action (Abraham "rose up" to obey God, 22:3). Joined here to el, "against," it marks Cain's rising as no accident -- it is aimed, like a weapon, straight at his own brother.
"slew him," vayyahargehu (וַיַּהַרְגֵהוּ). From harag, the ordinary Hebrew verb for violent killing. This is its first appearance in Scripture -- the first act of violent death in human history, coming not from an animal or a curse but from one brother's hand against another.
"my brother's keeper," hashomer achi (הֲשֹׁמֵר אָחִי). Shomer comes from shamar, "to keep, to guard" -- the very word used for Adam's charge in Eden, "to dress it and to keep [shamar] it" (2:15). Cain's flippant question denies the very role humanity was created to fill: not merely keeper of the ground, but keeper of one another.
"the voice of thy brother's blood," qol demei achikha (קוֹל דְּמֵי אָחִיךָ). Demei is the plural form of dam, "blood" -- literally "bloods." Jewish tradition long read this plural as pointing to more than one life lost: Abel's own blood, and with it every descendant he would never have, all silenced at once.
"crieth," tzo'aqim (צֹעֲקִים). From tsa'aq, the same verb used later for Israel's cry under Egyptian oppression, which God hears and answers (Exodus 3:7). Its plural form here matches "bloods" -- this is not a whisper but a scream, and it reaches God before Cain ever speaks another word.
Explanation
Verse 8 is stark and swift: in the field, away from eyes, "Cain rose up against Abel his brother, and slew him." The word "brother" tolls through these verses seven times in the chapter, pressing the horror: this is not only murder but the betrayal of the closest human bond. Verse 9 repeats the pattern of Eden: God comes asking, "Where is Abel thy brother?", the question of mercy that invites confession. Adam at least admitted fear; Cain answers with a lie and a sneer, "I know not: Am I my brother's keeper?" Verse 10 answers him with the terrible knowledge of God: "What hast thou done? the voice of thy brother's blood crieth unto me from the ground." Nothing hidden in a field is hidden from God; innocent blood has a voice, and heaven hears it.
Gospel Focus
The New Testament tells us what was behind the deed: Cain "was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous" (1 John 3:12). Envy of the righteous is the world's oldest hatred, and Jesus calls the devil "a murderer from the beginning" (John 8:44). And to Cain's sneering question the whole of Scripture answers yes: we are our brother's keeper, for "Whosoever hateth his brother is a murderer" (1 John 3:15), and love of neighbor is the second great command. But there is gospel here too. Hebrews says believers have come "to the blood of sprinkling, that speaketh better things than that of Abel" (Hebrews 12:24). Abel's blood cried from the ground for justice; the blood of Jesus cries from the mercy seat for pardon. The first blood shed on earth demanded judgment; the blood of the cross obtains mercy for all who come.
A Fugitive, Yet Marked with Mercy (Genesis 4:11-15)
The sentence falls on the murderer, yet even now God tempers judgment with protection. Cain laments his punishment, but not his sin.
The Mark of Cain
"And now art thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand; When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth. And Cain said unto the LORD, My punishment is greater than I can bear. Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me. And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him."
Hebrew Study
"cursed from the earth," arur atah min-ha'adamah (אָרוּר אַתָּה מִן־הָאֲדָמָה). The tiller of the ground is cursed from the very ground he tilled. It had opened its mouth to receive his brother's blood from his hand, and it will not henceforth yield unto him her strength.
"a fugitive and a vagabond," na vanad (נָע וָנָד). Cain is driven out to wander restless over the earth. The two words are a matched pair, and Cain repeats them back to God in his own protest -- the man who would not keep his brother is now to keep no place of his own.
"my punishment," avoni (עֲוֹנִי), my iniquity and its penalty. One Hebrew word carries both senses at once, so that Cain's complaint says more than he means. What he calls too great to bear is his iniquity as much as its sentence, the sin and its weight named together.
"a mark," ot (אוֹת), a sign. Even upon the first murderer God sets a protecting "mark" to restrain vengeance, mercy mingled with judgment. It is a sign, not a brand of shame -- placed there lest any finding him should kill him.
Explanation
In verses 11 and 12 the sentence matches the sin. The ground that received his brother's blood now turns against the tiller of the ground: it "shall not henceforth yield unto thee her strength," and the settled farmer is sentenced to wander, "a fugitive and a vagabond shalt thou be in the earth." In verses 13 and 14 Cain cries out, but listen closely: "My punishment is greater than I can bear." He grieves the consequences, exile, homelessness, the fear of being killed, and the hiding of God's face ("from thy face shall I be hid"), but he never says "I have sinned." Remorse over punishment is not repentance over sin. Verse 15 is unexpected mercy: God pledges sevenfold vengeance on anyone who kills Cain and sets "a mark upon Cain" to protect him. Scripture does not say what the mark was; it was a sign of protection, not of shame. Even the first murderer lives under a mercy he did not deserve, given space to repent.
Gospel Focus
God's dealing with Cain shows both His justice and His restraint. He does not take Cain's life; He guards it, for vengeance belongs to God alone (Romans 12:19). Yet Cain's lament warns us of a sorrow that saves no one. Paul writes that "godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death" (2 Corinthians 7:10). Cain wept over what sin cost him, never over what it was. Many still mourn consequences while clinging to the sin itself. The mark of Cain preaches a hard mercy: God is patient even with the guilty, "not willing that any should perish, but that all should come to repentance" (2 Peter 3:9), but patience refused becomes judgment in the end, for Jude warns of those who "have gone in the way of Cain" (Jude 11).
Cities, Crafts, and Lamech's Boast (Genesis 4:16-24)
Cain goes out from the presence of the LORD, and his line grows skilled and proud. Civilization advances while hearts move further from God, until Lamech turns the mercy shown to Cain into a song of vengeance.
Out from the Presence of the LORD
"And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden. And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch. And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech. And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah. And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle. And his brother's name was Jubal: he was the father of all such as handle the harp and organ. And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah. And Lamech said unto his wives, Adah and Zillah, Hear my voice; ye wives of Lamech, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt. If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold."
Hebrew Study
"Nod," Nod (נוֹד). The name means wandering. The man sentenced to be a wanderer settles in the land of Wandering itself, east of Eden, still further from the garden. Each move in Genesis eastward from Eden traces the widening distance between man and the presence of God.
Explanation
Verse 16 gives the saddest line in the chapter: "Cain went out from the presence of the LORD." In verse 17 Cain marries and builds a city, naming it for his son Enoch. His wife was necessarily a daughter of Adam (Genesis 5:4 says Adam "begat sons and daughters"); in the first generations, with mankind one family and the race genetically unmarred, such marriages were both unavoidable and not yet forbidden, the later law against them coming with Moses. Verses 18 through 22 trace Cain's line to Lamech and his children: Jabal, father of tent-dwelling herdsmen; Jubal, "the father of all such as handle the harp and organ"; and Tubal-Cain, "an instructer of every artificer in brass and iron" (an artificer is a craftsman). Human culture, agriculture, music, and metalwork flourish, real gifts of God's common grace, yet growing in a line walking away from Him. Skill is not the same as godliness.
Explanation
Verse 19 quietly notes another first: "Lamech took unto him two wives," the first departure from the one man, one woman pattern of Genesis 2:24. By verses 23 and 24 the line of Cain reaches its full flower in Lamech's war song. He boasts to his wives of killing a man for wounding him and twists God's protective word over Cain into a charter for his own revenge: "If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold." Sin has matured in seven generations from envy, to murder that still feared judgment, to murder set to music. Where Cain feared vengeance, Lamech celebrates it.
Gospel Focus
Lamech's "seventy and sevenfold" finds a deliberate answer on the lips of Jesus. When Peter asked how often he must forgive his brother, "till seven times?", Jesus answered, "I say not unto thee, Until seven times: but, Until seventy times seven" (Matthew 18:21-22). The arithmetic of Lamech's vengeance is overturned by the arithmetic of the kingdom's mercy. Two spirits run through history from this chapter: the way of Cain and Lamech, where self is avenged without limit, and the way of the woman's Seed, where grace forgives without limit. Every heart walks in one or the other.
Seth, and Calling on the Name of the LORD (Genesis 4:25-26)
The chapter that began with a birth of hope and fell into blood ends with another birth, and with worship. The promised line continues.
Another Seed
"And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew. And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD."
Hebrew Study
"Seth," Shet (שֵׁת). The line through which the Deliverer would come, cut off in Abel, is restored in Seth. Eve's own word "seed" (zera) in naming him reaches back to the promise of Genesis 3:15 -- she is watching for that promise still, after murder has taken one son and exile the other.
"appointed," shat (שָׁת). Another naming wordplay: Eve calls him Seth because God has "appointed" (shat) another seed. The name is a testimony in a single syllable -- the son was not merely born, he was given.
"call upon the name of the LORD," qara b'shem YHWH (קָרָא בְּשֵׁם יְהוָה). To call upon, invoke, and worship God by His name. The phrase later marks the worship of the patriarchs (Genesis 12:8; 26:25) and becomes the Bible's own definition of saving faith: "whosoever shall call on the name of the LORD shall be delivered" (Joel 2:32), words Peter quotes at Pentecost as "shall be saved" (Acts 2:21).
Explanation
Verse 25 answers the grief of the chapter. Abel is dead and Cain is exiled, but, in Eve's words, God "hath appointed me another seed." Eve's faith has matured; she no longer says "I have gotten"; now she confesses that God "hath appointed." The promise of 3:15 did not die in the field with Abel. Verse 26 closes the chapter with the birth of Enosh and a turning point: "then began men to call upon the name of the LORD." Over against Cain's line, building its cities out from God's presence, a line arises that is marked by one thing above all, calling on His name in worship and dependence. From here Genesis will follow this line of Seth down to Noah, to Abraham, and onward toward the Seed Himself.
Gospel Focus
To "call upon the name of the LORD" begins here and runs like a golden thread to the day of Pentecost, where Peter quotes Joel: "whosoever shall call on the name of the Lord shall be saved" (Acts 2:21), and then tells the crowd how to do it: "Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins" (Acts 2:38). The name by which God is savingly known was more fully revealed in Jesus, in whom the LORD Himself came to save; Paul was told, "arise, and be baptized, and wash away thy sins, calling on the name of the Lord" (Acts 22:16). What began with Enosh's generation, a people identified by calling on the name, finds its fullness in the church, which calls on the name of Jesus (1 Corinthians 1:2). The two lines of Genesis 4 still divide the world: those who go out from the presence of the LORD, and those who call on His name.
Chapter 4 in Review
Genesis 4 reveals how quickly sin spread beyond Eden. Cain and Abel bring offerings before the LORD. God accepts Abel's sacrifice, offered in faith from the firstborn of his flock, but rejects Cain's. When Cain becomes angry, God graciously warns him that sin is crouching at the door and urges him to rule over it. Cain ignores the warning, murders his brother, and answers God with the chilling question, "Am I my brother's keeper?" Though sentenced to wander the earth, he is shown unexpected mercy as God places a protective mark upon him. Cain's descendants establish cities, develop skilled trades, and produce music and metalworking, yet alongside these advances human violence reaches new heights in Lamech's proud boast of vengeance "seventy and sevenfold." God then raises up another seed through Seth. Enosh is born, and "then began men to call upon the name of the LORD."
For the Apostolic reader, this chapter sets two paths before every person. Abel's lamb, offered in faith, foreshadows the Lamb of God, and Abel's blood, which cried out from the ground for justice, is answered by the blood of Christ, which "speaketh better things," proclaiming mercy for all who believe. God's warning to Cain still speaks today: sin seeks entrance into every heart, but God provides both the warning and the grace to overcome it. The chapter closes with people calling upon the name of the LORD, a theme that reaches its fulfillment in the New Testament as salvation is proclaimed through the name of Jesus Christ. In obedience to the gospel, believers repent, are baptized in the name of Jesus Christ for the remission of sins, and receive the gift of the Holy Spirit, calling upon the only saving name revealed under heaven.
- God receives worship offered in faith from a right heart; He looks at the man before the gift (Hebrews 11:4).
- Sin crouches at the door, but by God's grace it can and must be mastered before it enters.
- Remorse over punishment is not repentance over sin; Cain grieved his sentence, never his brother.
- Abel's blood cried for justice; the blood of Jesus speaks better things, crying for mercy (Hebrews 12:24).
- God's covenant people are marked by calling on the name of the LORD, fulfilled in the New Testament as believers call on the saving name of Jesus in repentance and baptism (Acts 2:21, 38).
Questions for Reflection
- God asked Cain, "Why art thou wroth?" (that is, why are you angry?). What does your anger reveal about what your heart is trusting?
- Sin lies at the door. Is there a temptation you are entertaining at the doorstep instead of mastering?
- Cain asked, "Am I my brother's keeper?" Who has God placed in your care that you are tempted to disown?
- Do you call on the name of the LORD, in worship, in repentance, and in daily dependence?
