Verse-by-Verse Commentary
The Book of Genesis
Chapter 6: Noah Found Grace
Ten generations after Eden, sin has filled the earth. Every imagination of the thoughts of man's heart is only evil continually, and the God who made mankind is grieved at His heart. Judgment is announced: a flood will destroy all flesh. But one sentence turns the darkness: "But Noah found grace in the eyes of the LORD." God gives Noah a covenant, a plan, and a work, an ark of gopher wood by which his house will be saved. Genesis 6 is the anatomy of a corrupt world, and the blueprint of God's rescue.
About This Commentary
This is a verse-by-verse study of Genesis chapter 6. 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 6 records the corruption that brought the flood and the grace that saved a family. Where a passage is honestly debated, we say so plainly. Every Scripture quotation is from the King James Version.
Setting the Stage
Only Evil Continually
Sin has spread from one forbidden bite to a world where every imagination of the heart is evil, and the earth is filled with violence. Genesis 6 is the Bible's own diagnosis of how far the fall reaches.
Grieved at His Heart
God is not a distant judge. Man's sin grieves Him at heart. The flood is not cold anger but the sorrow of a Maker whose creature has ruined itself.
But Noah
The first mention of grace in the Bible falls on one man in a doomed world: "Noah found grace in the eyes of the LORD." Grace precedes the ark; God's favor comes before Noah's work.
The Ark
God gives exact dimensions for a vessel of salvation and establishes His covenant with Noah. The ark becomes Scripture's great early picture of salvation: one door, one refuge, and safety for all inside.
The Sons of God and the Daughters of Men (Genesis 6:1-4)
As mankind multiplies, a corrupting intermingling spreads, and God sets a limit on the years of His striving.
My Spirit Shall Not Always Strive
"And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them, That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose. And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years. There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown."
Honest Note on a Debated Passage
Who are "the sons of God"? Faithful believers have long held different views on this difficult passage, and we believe it is best to state them honestly.
One view, commonly held among Apostolic Pentecostal teachers, understands the phrase in the flow of Genesis 4 and 5. According to this view, the "sons of God" are the godly line of Seth, the people who began to "call upon the name of the LORD" (Genesis 4:26), while the "daughters of men" represent the ungodly line. As the godly line abandoned spiritual separation and chose wives based only on outward beauty, "of all which they chose," the distinction between the godly and the ungodly became increasingly blurred, contributing to the widespread corruption that soon filled the earth.
Another ancient interpretation, found in some Second Temple Jewish writings and adopted by many early Christian writers, understands the "sons of God" to be angelic beings (as the phrase is used in Job 1:6) who rebelled against God and took human wives. Those who reject this interpretation point to Jesus' statement that the angels in heaven "neither marry, nor are given in marriage" (Matthew 22:30), arguing that such unions are inconsistent with the nature of angels.
The Hebrew word Nephilim, traditionally translated "giants" in the KJV, has been understood in different ways throughout history, and its precise meaning remains debated. Genesis associates them with the "mighty men which were of old, men of renown" (Genesis 6:4), emphasizing the extraordinary and violent character of that generation.
Whichever interpretation one adopts concerning the identity of the "sons of God," the central message of the passage is clear: humanity abandoned God's order, wickedness spread throughout the earth, violence filled society, and God's righteous judgment followed.
Hebrew Study
"strive," yadon (יָדוֹן). A rare and much-debated root, understood by many to mean "to remain, to abide," so that the verse reads: God's Spirit will not remain in man forever, striving against sin without end -- His patience has a limit.
"flesh," basar (בָּשָׂר). Man is named by his weakness, not his strength -- flesh, not spirit -- the very ground of the limit God sets, for it is the fleshly, mortal side of man that will not go on being strengthened by God's Spirit forever.
"giants," nefilim (נְפִלִים). As mankind multiplies, corruption spreads, and God sets a limit on His striving Spirit and on the span of human life, "an hundred and twenty years." It is in those same days, the verse says, that the nefilim were in the earth -- the age in which God draws a boundary is also the age of these towering figures.
"men of renown," anshei hashem (אַנְשֵׁי הַשֵּׁם), men of the name. The earth fills with proud "men of renown" -- men who made a name for themselves, in ironic contrast to the God who alone gives a name that lasts. Their fame is the last thing the record says of them before it turns to the wickedness that brings the flood.
Explanation
Verse 3 records God's response: "My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years." God's Spirit had been striving with humanity, contending, warning, and calling people to repentance. The flood did not come upon a world God had left without witness.
Many interpreters understand the "hundred and twenty years" as the period of God's patience before the flood, during which Noah built the ark and, as Peter later calls him, "a preacher of righteousness" (2 Peter 2:5). Others understand it as a limitation God placed on human lifespan after the flood. Either way, the point is unmistakable: God's patience has an appointed limit. He delays judgment to extend mercy, but His warnings will not continue forever.
Gospel Focus
Two abiding lessons stand out. First, God's people lose their distinctiveness when they abandon God's order and compromise with the world. If the Sethite interpretation is correct, the godly line that had called upon the name of the LORD forsook spiritual separation by choosing wives according to outward appearance rather than godly character. Even if one holds another interpretation, the chapter unmistakably shows that the boundary between righteousness and wickedness collapsed, corruption spread throughout society, and violence filled the earth. Scripture therefore consistently calls God's people to spiritual separation and instructs believers to marry "only in the Lord" (1 Corinthians 7:39; 2 Corinthians 6:14).
Second, the Spirit's striving has a limit. God is longsuffering, "not willing that any should perish" (2 Peter 3:9), yet the day of grace is not endless. "To day if ye will hear his voice, harden not your hearts" (Hebrews 3:15). Noah's generation received years of warning before judgment came. God's patience is great, but it should never be mistaken for indifference. His mercy invites repentance, yet His judgment will come upon all who refuse His call.
The Wickedness of Man Was Great (Genesis 6:5-8)
Heaven's verdict on the pre-flood world reaches all the way into the thoughts of the heart, and God's own heart is grieved. Then comes the Bible's first word of grace.
But Noah Found Grace
"And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented the LORD that he had made man on the earth, and it grieved him at his heart. And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them. But Noah found grace in the eyes of the LORD."
Hebrew Study
"repented," nacham (נָחַם). The word translated "repented" is the same root as "comfort" in Noah's name (5:29). When the KJV says "it repented the LORD," the old word means He was moved with sorrow. This is the language of relationship, not of a God who made a mistake; Scripture is clear that God is not a man that He should repent as men do (Numbers 23:19).
"grieved," atsab (עָצַב). This word is related to the "sorrow" of the curse (3:16-17). Man's sin brought sorrow into God's own heart -- the same word that named the pain the fall let loose in the world now names what that world does to its Maker. It tells us how the unchanging God truly feels toward sin: grieved.
"grace," chen (חֵן). Favor freely given. This is the first occurrence of the word in the Bible, and it appears not after Noah's obedience but before it, in the middle of a world sentenced to death.
Explanation
Verse 5 is the deepest diagnosis of sin in the Old Testament. The wickedness was "great in the earth," outward and visible, but God saw further: "every imagination of the thoughts of his heart was only evil continually." Every imagination; only evil; continually. Sin is not a surface stain but a spring polluted at the source, the heart. Verses 6 and 7 give heaven's response: grief, and a sentence of destruction on man and the creatures of his world. Then verse 8, one of the great "buts" of the Bible: "But Noah found grace in the eyes of the LORD." The flood narrative does not begin with Noah's goodness; it begins with God's grace.
Gospel Focus
Genesis 6:5 is why the gospel must be more than moral advice. If every imagination of the thoughts of the heart is evil, then what man needs is not improvement but a new heart, exactly what God promised, "A new heart also will I give you, and a new spirit will I put within you" (Ezekiel 36:26), and what the new birth of water and Spirit accomplishes (John 3:5; Titus 3:5). And the order of verse 8 is the order of all salvation: grace found Noah before Noah built anything. "By grace are ye saved through faith... not of works" (Ephesians 2:8-9). The man who found grace then worked for a hundred years, but the work flowed from the grace, never the grace from the work. So it remains: God's favor comes first, and obedient faith answers it.
Noah Walked with God (Genesis 6:9-12)
Against a world corrupt and violent, one household stands in covenant fellowship with God.
Just, Blameless, Walking with God
"These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God. And Noah begat three sons, Shem, Ham, and Japheth. The earth also was corrupt before God, and the earth was filled with violence. And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth."
Hebrew Study
"just," tsaddiq (צַדִּיק). Noah is the first man Scripture calls "just," righteous. The word is set on him in the very passage that calls the earth around him corrupt and filled with violence -- one just man named against a whole world.
"perfect," tamim (תָּמִים). "Perfect" does not mean sinless but whole, blameless, a man of integrity "in his generations," amid his corrupt contemporaries. The source of both this and his righteousness is the third phrase of the verse: like Enoch before him, "Noah walked with God."
"corrupt," shachat (שָׁחַת). The verb "corrupt" appears three times in verses 11 and 12, and the same root will describe what God does in judgment ("destroy," verse 13): the world had already ruined itself, and God's judgment hands it over to what it had chosen.
"violence," chamas (חָמָס). "Violence" is the fruit of that corruption: a world of cruelty, oppression, and bloodshed. The earth is not merely stained with it but filled with it, so that what men did to one another is named alongside their ruin as the reason judgment came.
Explanation
Verses 9 and 10 introduce the new toledot, the account of Noah, with a three-fold portrait: just before God, blameless before men, and walking with God daily. Verse 11 and 12 paint the backdrop twice over: "corrupt... corrupt... corrupted," and "filled with violence." When God "looked upon the earth," He found all flesh had ruined its own way. One family's lamp burned in that darkness. Righteousness in Scripture is never proved by easy surroundings; Noah was blameless "in his generations," precisely where blamelessness cost the most.
Gospel Focus
Hebrews tells us the spring of Noah's righteousness: "By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house," and so "became heir of the righteousness which is by faith" (Hebrews 11:7). His righteousness was of faith, evidenced by obedience, the only kind of righteousness the Bible knows. And his life answers a question every believer asks: can anyone live godly in a wholly ungodly age? Noah did, and Peter says God is still able to "deliver the godly out of temptations" while reserving the unjust for judgment (2 Peter 2:9). What was possible for Noah in his generation is possible in every generation: by walking with God, a believer can live in the midst of a corrupt world and not be carried along by it.
Make Thee an Ark (Genesis 6:13-16)
God announces the end of all flesh, and in the same breath gives the design of salvation, exact, practical, and sufficient.
Gopher Wood, Rooms, and Pitch
"And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth. Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch. And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits. A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it."
Hebrew Study
"violence," chamas (חָמָס). A word for wrong done by force -- lawless cruelty, not mere immorality -- naming the specific sin that finally moves God to judgment: a world where the strong preyed on the weak without restraint.
"ark," tevah (תֵּבָה), a chest or vessel. The very same rare word is used only one other time in the whole Old Testament: the little basket of bulrushes that carried the infant Moses safely through the water (Exodus 2:3, 5). Both are called tevah, and both hold a helpless remnant afloat over water sent in judgment -- one word joining Noah's flood to Israel's deliverer.
"gopher wood," atzei-gofer (עֲצֵי־גֹפֶר). This word appears nowhere else in the Bible, and its precise identity is simply unknown to us -- one detail Scripture leaves unexplained, a reminder that not every question the text raises is meant to be answered.
"pitch," kofer (כֹּפֶר), a covering. God announces judgment on a world "filled with violence" and gives Noah exact instructions for the ark, the one vessel of salvation, sealed with "pitch" (kofer, the same root as "atonement, covering") against the coming flood.
Explanation
Verse 13 states the sentence plainly to Noah; God does not hide His purposes from the man who walks with Him (compare Amos 3:7). Verses 14 through 16 give the plan. The ark, Hebrew tevah, is a chest or box, a vessel built not to sail anywhere but to float and preserve. Its dimensions are shipyard-practical: three hundred cubits by fifty by thirty, roughly 450 feet long, 75 wide, and 45 high with an eighteen-inch cubit, proportions remarkably like those of modern cargo vessels, with a window course near the roof, three stories (decks), rooms ("nests") within, and pitch sealing it inside and out. This is not mythology's magic boat; it is a real design for a real rescue. And note one detail with a long shadow: "the door of the ark shalt thou set in the side thereof," one door, and only one, into safety.
Gospel Focus
The ark is the Bible's first great picture of salvation in Christ. One vessel, prepared by God's own design, carried through judgment all who entered; everything outside it perished. One door stood in its side, and Jesus says, "I am the door: by me if any man enter in, he shall be saved" (John 10:9). The pitch (kopher) that sealed it shares its root with the great word for atonement covering, kaphar; the vessel of rescue was covered within and without. Peter completes the picture for the church: in the ark "eight souls were saved by water," and "the like figure whereunto even baptism doth also now save us" (1 Peter 3:20-21); a "like figure" is the old way of saying a matching picture, a counterpart. The waters that judged the old world floated the ark and carried God's people into a new one, as baptism buries the old life and raises us to walk in newness of life (Romans 6:4). God still saves the way He saved then: by grace, through faith, in the one vessel He Himself has provided.
With Thee Will I Establish My Covenant (Genesis 6:17-22)
Judgment is coming on all flesh, but God binds Himself to Noah with the Bible's first named covenant, and Noah answers with complete obedience.
Thus Did Noah
"And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die. But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee. And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female. Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive. And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them. Thus did Noah; according to all that God commanded him, so did he."
Hebrew Study
"covenant," berit (בְּרִית). The first appearance of the Bible's great covenant word. A covenant is God binding Himself by promise. Before a drop of rain falls, God commits Himself to Noah's preservation: "with thee will I establish my covenant." Salvation rests not on the ark's timbers but on God's sworn word.
Explanation
Verse 17 declares the means of judgment, and God takes personal responsibility: "I, even I, do bring a flood of waters upon the earth." The flood is no accident of nature but the act of the Judge of all the earth. Verse 18 sets the "but" of covenant grace against it: Noah and his household, eight persons, will go into the ark. Verses 19 through 21 widen the rescue to the creatures: two of every sort, male and female, with fowls, cattle, and creeping things "after their kind" coming to Noah, and food stored for all. God's mercy in judgment reaches even the animals He made. Then verse 22, one of the finest obituaries of faith in the Bible: "Thus did Noah; according to all that God commanded him, so did he." No editing of the plan, no partial obedience, no delay. For roughly a century, against all appearances, in the face of a mocking world, Noah simply did all that God said.
Gospel Focus
Grace found Noah; the covenant secured him; and obedience carried him into the ark. Scripture holds these together without embarrassment, and so must we. Peter calls Noah "a preacher of righteousness" (2 Peter 2:5); for a hundred and twenty years the half-built ark itself was a sermon, and "the longsuffering of God waited" (1 Peter 3:20) while he preached. Jesus made those days a mirror of the last: "as the days of Noe were, so shall also the coming of the Son of man be" (Matthew 24:37-39), people eating, drinking, and marrying, unaware until the flood came. The application writes itself: God has again announced judgment, again provided one vessel of safety, and again stretched out a season of longsuffering. The wise answer is Noah's answer: according to all that God has commanded, so do, and enter in before the door is shut.
Chapter 6 in Review
Genesis 6 diagnoses a dying world and unveils a saving God. The boundary between the godly and the ungodly collapsed, and wickedness grew until every imagination of the thoughts of man's heart was only evil continually. God, grieved at His heart, set a limit to His Spirit's striving and announced the flood. But Noah found grace in the eyes of the LORD: a just man, blameless in his generations, who walked with God. God gave him the design of the ark, bound Himself in covenant to save his house, and Noah did according to all that God commanded him.
For the Apostolic reader, the chapter is a portrait of salvation from first to last. Grace comes first, and obedient faith answers it; the one ark with its one door pictures the one Savior; and the water that judged the world and saved the eight looks forward, as Peter says, to baptism. And the days of Noah are the mirror Jesus held up to our own: a world absorbed and unaware, a God patiently warning, and a door that will one day close. Blessed are those who, like Noah, walk with God and do all that He commands.
- Sin's reach is total: "every imagination of the thoughts of his heart was only evil continually" (6:5).
- Man's sin grieves the heart of God; judgment flows from wounded love, not cold anger.
- Grace precedes works: Noah found grace before he built anything (6:8; Ephesians 2:8-9).
- The ark pictures Christ: one God-designed refuge, one door, and safety through judgment; its waters point to baptism (1 Peter 3:20-21).
- The Spirit's striving has a limit; the day of grace is long, but it is not endless (6:3).
Questions for Reflection
- The sons of God chose wives by sight alone. Where are you letting the world set your standards?
- Noah was blameless "in his generations," in the hardest of times. What would walking with God look like in yours?
- "Thus did Noah; according to all that God commanded him." Is there a command of God you are editing or delaying?
