Verse-by-Verse Commentary
The Book of Isaiah
Chapter 50: I Gave My Back to the Smiters
Chapter 50 holds the third of Isaiah's Servant Songs. God begins by answering Israel's despair: they were not cast off because His arm is too short to save, but because of their own sins. Then the Servant speaks. He has 'the tongue of the learned,' a listening ear opened by God morning by morning, and a will wholly surrendered, 'I was not rebellious, neither turned away back.' And that surrender leads Him straight into suffering: 'I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting.' Yet He is unshaken, for 'the Lord GOD will help me,' and He sets His face 'like a flint,' certain He will not be ashamed.

For each section you will find the KJV text, the Hebrew words that sharpen the meaning, plain explanation, and a Gospel Focus. This chapter shows a Servant who obeys perfectly and suffers willingly, and it lays out the choice between trusting the LORD and walking by our own kindled fire. Every Scripture quotation is from the King James Version.
Setting the Stage
Is My Hand Shortened?
Israel was not sold off because God is weak, but because of her sins. His arm still dries up the sea.
The Tongue of the Learned
The Servant listens each morning and speaks a word in season to the weary, with a will that never turns back.
My Back to the Smiters
Obedience leads Him into shame and spitting; He hides not His face, yet sets it like a flint.
Trust, or Your Own Fire
Fear the LORD and stay upon your God, or kindle your own light and lie down in sorrow.
Is My Hand Shortened, That It Cannot Redeem? (Isaiah 50:1-3)
God answers the exiles who felt permanently divorced and abandoned: there is no bill of divorcement; they were sold for their own iniquities, and the God who dries up the sea is more than able to redeem them if they will only answer His call.
Not Cast Off For Weakness, But For Sin
"Thus saith the LORD, Where is the bill of your mother's divorcement, whom I have put away? or which of my creditors is it to whom I have sold you? Behold, for your iniquities have ye sold yourselves, and for your transgressions is your mother put away. Wherefore, when I came, was there no man? when I called, was there none to answer? Is my hand shortened at all, that it cannot redeem? or have I no power to deliver? behold, at my rebuke I dry up the sea, I make the rivers a wilderness: their fish stinketh, because there is no water, and dieth for thirst. I clothe the heavens with blackness, and I make sackcloth their covering."
Hebrew Study
"divorcement," keritut (כְּרִיתֻת), from a root meaning "to cut off." A legal certificate that permanently severed a marriage. God asks to see the paper, and there is none. He never cut Israel off; her exile was chastening, not divorce, and the way home stood open.
"Is my hand shortened," haqatsor qatserah yadi (הֲקָצוֹר קָצְרָה יָדִי). A vivid Hebrew idiom for lacking power. The same picture appears in Numbers 11:23, "Is the LORD's hand waxed short?" The problem was never a short arm in heaven; it was a deaf ear on earth.
Explanation
The exiles felt like a cast-off wife and sold-off children, permanently abandoned by God. He answers with two piercing questions. First, where is the divorce certificate? There is none, because He never divorced them. Second, to which creditor did He sell them to pay a debt? None, because He owed no one. The truth is the reverse: "for your iniquities have ye sold yourselves." They were not victims of God's weakness or poverty; they were captives of their own sin. Then God turns to the deeper wound: "when I came, was there no man? when I called, was there none to answer?" The failure was not on His side but theirs, no response, no faith. And to any who imagine His arm too weak to bring them home, He points to His power over creation: "at my rebuke I dry up the sea", the very act of the Exodus, and He clothes the heavens in blackness. The God who split the Red Sea and darkened Egypt is not too weak to redeem; He is only waiting for someone to answer when He calls.
Gospel Focus
How many people carry the same lie the exiles believed, that God has divorced them, written them off, and can no longer be bothered to save. Here is the answer: there is no bill of divorcement. God has not cast you off. Your troubles are the fruit of sin, yours and Adam's, not the sign of a God too weak or too poor to redeem. And the cross settles the question of His power and His willingness forever. "Is my hand shortened at all, that it cannot redeem?" The hand that "dries up the sea" is the same hand that was pierced to buy you back. When Jesus "came," the tragedy Isaiah named was fulfilled, "he came unto his own, and his own received him not" (John 1:11), "was there no man... none to answer?" Yet He redeemed anyway. The only thing that keeps a soul in exile now is refusing to answer when He calls, "To day if ye will hear his voice, harden not your hearts" (Hebrews 3:15). Answer Him. His arm is not shortened. His power is not spent. The way home is open, and He is calling your name.
I Gave My Back to the Smiters (Isaiah 50:4-6)
The Servant speaks. God has given Him a taught tongue to strengthen the weary and an opened ear to obey, and His perfect obedience carries Him willingly into suffering, His back to the whips, His cheeks to the pluckers, His face to shame and spitting.
The Learned Tongue and the Willing Back
"The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned. The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back. I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting."
Hebrew Study
"the tongue of the learned," leshon limmudim (לְשׁוֹן לִמּוּדִים). Literally "the tongue of the taught ones," a disciple's tongue. The Servant speaks not His own words but words learned from God, so that He can "speak a word in season to him that is weary." He is the perfect Disciple who became the perfect Teacher.
"a word in season," davar la-ya'ef (דָּבָר לַיָּעֵף). A well-timed word "to him that is weary." The Servant's speech is aimed at exhaustion and heartbreak, exactly as Jesus said, "Come unto me, all ye that labour and are heavy laden, and I will give you rest" (Matthew 11:28).
Explanation
Now the Servant Himself speaks, and every line is remarkable. He has "the tongue of the learned", a taught, disciplined tongue, so He knows "how to speak a word in season to him that is weary." His words are timed for the tired and the broken. And where does He get them? From listening: "he wakeneth morning by morning, he wakeneth mine ear to hear as the learned." Every morning the Servant listens like a pupil before He speaks like a teacher. Then comes the heart of His obedience: "The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back." Unlike Israel, who would not answer, the Servant answers perfectly, no rebellion, no turning away. But notice where obedience leads Him: straight into suffering. "I gave my back to the smiters" (He gave it; it was not merely taken), "and my cheeks to them that plucked off the hair", a gross insult and torment, "I hid not my face from shame and spitting." The obedient Servant does not run from the whip, the beard-plucking, or the spit. He offers Himself to it, freely, for us.
Gospel Focus
This is Jesus, foretold seven centuries before Calvary in astonishing detail. He is the One with "the tongue of the learned," of whom the officers said, "Never man spake like this man" (John 7:46), whose whole ministry was a "word in season" to weary souls. He is the One whose ear was "opened," who lived to say, "I do always those things that please him" (John 8:29), and "not my will, but thine, be done" (Luke 22:42). And He is the One who "gave" His back to the smiters. Matthew records the fulfillment word for word: "Then did they spit in his face, and buffeted him; and others smote him with the palms of their hands" (Matthew 26:67), and "they... took the reed, and smote him on the head" (Matthew 27:30). Isaiah saw the plucked beard, the whip, and the spit centuries ahead of time. And every blow was given, not seized: "I gave my back." No one took Jesus' life; He laid it down, "I lay down my life... No man taketh it from me, but I lay it down of myself" (John 10:17-18). The willing suffering of the Servant is the measure of His love. He did not hide His face from your shame; He took it, so that you would never have to.
I Have Set My Face Like a Flint (Isaiah 50:7-9)
In the midst of suffering the Servant is unshaken, for the Lord GOD is His help. He sets His face like flint, confident of vindication: the One who justifies Him is near, and every accuser will wear out like a moth-eaten garment.
He Is Near That Justifieth Me
"For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed. He is near that justifieth me; who will contend with me? let us stand together: who is mine adversary? let him come near to me. Behold, the Lord GOD will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up."
Hebrew Study
"set my face like a flint," samti panai ka-challamish (שַׂמְתִּי פָנַי כַּחַלָּמִישׁ). Flint is the hardest of stones. The Servant's face is set with unbreakable resolve toward His task. Luke uses the very picture of the road to the cross: "he stedfastly set his face to go to Jerusalem" (Luke 9:51).
"He is near that justifieth me," qarov matsdiqi (קָרוֹב מַצְדִּיקִי). The word matsdiqi is courtroom language, "the one who declares me righteous." The same root, tsadaq, runs through Paul's doctrine of justification. God vindicated His Servant by raising Him from the dead.
Explanation
How can the Servant endure the whip and the spit without breaking? The answer is here, repeated three times for emphasis: "the Lord GOD will help me." Because God is His helper, He "shall not be confounded", not put to shame, not disgraced. So He sets His face "like a flint", hard as the hardest stone, immovable in His resolve. Then the scene becomes a courtroom. The Servant is confident of acquittal: "He is near that justifieth me." He throws down a challenge to every accuser, "who will contend with me? let us stand together", let My adversary step forward and make his case. And He knows the outcome: "who is he that shall condemn me?" No one can, because the Judge is on His side. His accusers, who seem so powerful now, will simply wear out and crumble, "they all shall wax old as a garment; the moth shall eat them up." Their case has no future. God's Servant will be vindicated.
Gospel Focus
The Servant's flint-set face is the face of Jesus turned toward Calvary, "he stedfastly set his face to go to Jerusalem" (Luke 9:51). He endured the cross not because He felt nothing, but because He trusted the Father who would help Him, "for the joy that was set before him endured the cross, despising the shame" (Hebrews 12:2). And the courtroom language points to the resurrection. On Good Friday it looked as if the Servant had been condemned; on Easter God declared, "He is near that justifieth me," raising Jesus and thereby vindicating Him, "justified in the Spirit" (1 Timothy 3:16). But here is the wonder for us: Paul takes these very words and hands them to every believer. "Who shall lay any thing to the charge of God's elect? It is God that justifieth. Who is he that condemneth? It is Christ that died" (Romans 8:33-34). The Servant's confidence becomes ours. Because Jesus stood justified, the accuser has no case against you either. Set your face like a flint. The One who justifies you is near, and every charge against you will wear out like a moth-eaten rag.
Trust the LORD, or Walk by Your Own Fire (Isaiah 50:10-11)
The chapter closes with two paths. The believer in the dark is told to trust the name of the LORD and lean on his God; the self-reliant, who kindle their own light, are warned they will lie down in sorrow.
Stay Upon His God, Not Your Own Sparks
"Who is among you that feareth the LORD, that obeyeth the voice of his servant, that walketh in darkness, and hath no light? let him trust in the name of the LORD, and stay upon his God. Behold, all ye that kindle a fire, that compass yourselves about with sparks: walk in the light of your fire, and in the sparks that ye have kindled. This shall ye have of mine hand; ye shall lie down in sorrow."
Hebrew Study
"stay upon his God," yishaen b-elohav (יִשָּׁעֵן בֵּאלֹהָיו). The verb shaan means to lean, to support one's whole weight on something. In the dark, the believer does not lean on his own understanding but leans his entire weight on God, as Proverbs urges, "Trust in the LORD with all thine heart; and lean not unto thine own understanding" (Proverbs 3:5).
"sparks that ye have kindled," ziqot bi'artem (זִיקוֹת בִּעַרְתֶּם). The self-made torches of those who refuse to trust God in the dark. Their own light burns out fast and leaves them in "sorrow," a homemade fire is no substitute for the light of God.
Explanation
The chapter ends by turning to us with two portraits. The first is the God-fearer walking through a dark season: "Who is among you that feareth the LORD, that obeyeth the voice of his servant, that walketh in darkness, and hath no light?" Notice, even the obedient believer can walk "in darkness" with "no light", faith does not exempt us from dark valleys. What is the God-fearer to do? Not panic, not scheme, but trust: "let him trust in the name of the LORD, and stay upon his God." When you cannot see the way, lean your full weight on the God you cannot see. The second portrait is the opposite: "all ye that kindle a fire, that compass yourselves about with sparks." These are the self-reliant, who will not wait on God in the dark but light their own torches and walk by their own sparks. God's word to them is sobering, "walk in the light of your fire", have it your way, and reap it, "This shall ye have of mine hand; ye shall lie down in sorrow." The self-made fire cannot last, and it ends in grief.
Gospel Focus
These two verses lay out the whole gospel choice: trust God's light, or make your own. The believer who "walketh in darkness, and hath no light" is not told to manufacture light but to trust the Lord and lean hard on Him. This is faith at its purest, holding on to God in the dark when you cannot feel or see Him. Jesus is that Light. "I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life" (John 8:12). To walk by your own sparks is to try to save yourself, to light your own path by your own works, your own wisdom, your own religion. It always burns out, and it always ends the same way, "ye shall lie down in sorrow." But to fear the LORD and stay upon your God is to trust the finished work of the Servant who gave His back to the smiters for you. When your night is darkest and you have no light of your own, do not kindle your own fire. Trust the name of the LORD Jesus, lean your whole weight on Him, and He will bring you through to morning.
Chapter 50 in Review
Isaiah 50 opens with God clearing His name: Israel was never divorced or sold off because He was too weak or too poor to keep her, "Is my hand shortened at all, that it cannot redeem?" She went into exile for her own sins, and the God who "dries up the sea" is more than able to bring her home, if only she will answer when He calls. Then the Servant speaks. He has a taught, disciple's tongue for the weary and a listening ear opened morning by morning, and His perfect obedience leads Him not to comfort but to suffering: "I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting." Yet He is unbroken, because "the Lord GOD will help me." He sets His face "like a flint," certain of vindication: "He is near that justifieth me... who is he that shall condemn me?" The chapter ends with the choice it presses on every reader, trust the LORD in the dark, or walk by your own sparks and lie down in sorrow.
For the Apostolic reader this is a portrait of Jesus painted seven hundred years early. The smitten back, the plucked cheeks, the shame and the spitting were all fulfilled to the letter in His passion, and every blow was given, not merely taken, for no man took His life; He laid it down of Himself. His flint-set face is the face turned toward Jerusalem and the cross; His confidence, "He is near that justifieth me," was answered in the resurrection, and Paul hands that same confidence to us, "It is God that justifieth. Who is he that condemneth?" And the final call is the gospel itself: when you walk in darkness with no light, do not kindle your own fire. Trust the name of the LORD, lean your whole weight on the Servant who suffered for you, and He will be your light.
- God did not cast off His people for weakness but because of their sins; His arm is not shortened (50:1-2; John 1:11; Hebrews 3:15).
- The Servant has "the tongue of the learned" and a listening ear, speaking "a word in season" to the weary (50:4; Matthew 11:28; John 7:46).
- He willingly "gave" His back to the smiters and His face to shame and spitting, fulfilled exactly in Christ's passion (50:6; Matthew 26:67; John 10:17-18).
- Because "the Lord GOD will help me," He set His face "like a flint" toward the cross and was vindicated (50:7-9; Luke 9:51; Hebrews 12:2).
- Every believer's confidence: "It is God that justifieth. Who is he that condemneth?" (50:8-9; Romans 8:33-34).
- In the dark, trust the LORD and lean on Him; do not walk by your own sparks and lie down in sorrow (50:10-11; John 8:12; Proverbs 3:5).
Questions for Reflection
- Do you secretly believe God has "divorced" you or is too weak to redeem your situation? How does verse 2 answer that?
- The Servant listened "morning by morning" before He spoke. What place does listening to God have in your mornings?
- Jesus gave His back to the smiters; no one forced Him. How does the willingness of His suffering deepen your love for Him?
- When you walk in darkness with no light, are you tempted to kindle your own fire? What would it look like to simply "stay upon" your God instead?
