Verse-by-Verse Commentary
The Book of Isaiah
Chapter 1: Though Your Sins Are Like Scarlet
Isaiah opens like a courtroom. God calls heaven and earth as witnesses and lays out His charge against a people who honor Him with religious ceremony while their hearts and hands are far from Him. It is a searching indictment of empty worship. Yet even here, in the middle of the accusation, God does something only God would do: He extends His hand in mercy, inviting the guilty to reason with Him, and offering to wash scarlet sins white as snow.
About This Commentary
This is a verse-by-verse study of Isaiah chapter 1. For each section you will find the KJV text, the Hebrew words that sharpen the meaning, plain explanation, and a Gospel Focus. Isaiah is the greatest of the writing prophets, and it opens with both a sharp rebuke of hollow religion and a stunning offer of cleansing. Every Scripture quotation is from the King James Version.
Setting the Stage
The Gospel Prophet
Isaiah is so full of the coming Messiah, His virgin birth, His suffering, His reign, that he is often called the gospel prophet. The book moves from judgment to comfort to salvation.
Isaiah the Prophet
Isaiah son of Amoz prophesied in Judah over the reigns of four kings, roughly 740 to 680 BC. His name means "the LORD is salvation," the very theme of his book.
Judah on Trial
Chapter 1 is a summary indictment of Judah: outwardly religious, inwardly rebellious, ripe for judgment yet still offered mercy. It sets the tone for all that follows.
Religion or Repentance
God is not impressed by sacrifices offered by unclean hands. He wants changed hearts and just lives, and He offers to cleanse those who will come to Him.
A People Who Have Forsaken the LORD (Isaiah 1:2-4)
God summons heaven and earth to hear His complaint against children who have rebelled against their Father.
My People Do Not Consider
"The vision of Isaiah the son of Amoz, which he saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah. Hear, O heavens, and give ear, O earth: for the LORD hath spoken, I have nourished and brought up children, and they have rebelled against me. The ox knoweth his owner, and the ass his master's crib: but Israel doth not know, my people doth not consider. Ah sinful nation, a people laden with iniquity, a seed of evildoers, children that are corrupters: they have forsaken the LORD, they have provoked the Holy One of Israel unto anger, they are gone away backward. Why should ye be stricken any more? ye will revolt more and more: the whole head is sick, and the whole heart faint. From the sole of the foot even unto the head there is no soundness in it; but wounds, and bruises, and putrifying sores: they have not been closed, neither bound up, neither mollified with ointment. Your country is desolate, your cities are burned with fire: your land, strangers devour it in your presence, and it is desolate, as overthrown by strangers. And the daughter of Zion is left as a cottage in a vineyard, as a lodge in a garden of cucumbers, as a besieged city. Except the LORD of hosts had left unto us a very small remnant, we should have been as Sodom, and we should have been like unto Gomorrah. Hear the word of the LORD, ye rulers of Sodom; give ear unto the law of our God, ye people of Gomorrah. To what purpose is the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats. When ye come to appear before me, who hath required this at your hand, to tread my courts? Bring no more vain oblations; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting. Your new moons and your appointed feasts my soul hateth: they are a trouble unto me; I am weary to bear them. And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood."
Hebrew Study
Isaiah opens like a courtroom, summoning "heavens" and "earth" as witnesses in God's lawsuit against His children. The indictment turns on one word: "Israel doth not know" — yada, to know intimately. "The ox knoweth his owner, and the ass his master's crib: but... my people doth not consider" (hitbonan, from bin, "to discern, to perceive with the mind" -- a different verb from "know," pairing an intimate relational failure with a failure even to reflect). Even dumb beasts recognize the hand that feeds them; God's own people neither know nor stop to think. It is a stinging picture of ingratitude — a nation "laden with iniquity," heavy-loaded, that has "forsaken the LORD" who reared it.
Explanation
God's first complaint is one of stunning ingratitude. Even a dumb animal knows the hand that feeds it, returning each night to its owner's stall; but God's own people, reasoning creatures made in His image, do not know or consider their Maker. The comparison is deliberately humbling. The beasts show more sense of belonging than the nation God raised as His own children.
Gospel Focus
The root sin here is not first idolatry or injustice but simply failing to "consider," to stop and reckon with God. Sin thrives on thoughtlessness; we drift from God not usually by a sudden decision but by ceasing to remember Him. The prodigal began to come home when "he came to himself" (Luke 15:17). The call of this verse is to consider: to remember who owns us, who feeds us, who made us His own. An ox knows its master. Do we know ours?
I Have Had Enough of Your Sacrifices (Isaiah 1:11-17)
God rejects the worship of people whose hands are full of violence, and tells them what He truly requires.
Wash Yourselves; Learn to Do Good
"Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil; Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow."
Hebrew Study
God rejects worship divorced from justice — the endless sacrifices are "vain oblations," their feasts a weariness to Him — and calls instead for cleansing that shows itself in action: "Wash you, make you clean" (rachatsu hizzaku, from rachats, ordinary bathing turned into a call for inward cleansing) "... cease to do evil; learn to do well" (yatav, the root behind the everyday word "good," here made into a discipline to be learned, not a feeling to be felt); "seek judgment" (mishpat, one of the great words of the prophets, meaning justice done and rights upheld, not merely a verdict passed), "relieve the oppressed, judge the fatherless, plead for the widow." The Hebrew for "relieve the oppressed" means to set right what is wrong. Ritual without righteousness is not worship God will accept; the clean hands He wants are hands that defend the weak.
Explanation
God says He is weary of their feasts, sacrifices, and even their prayers, not because He dislikes worship, but because their worship was a mask over injustice and violence. True religion, He says, shows itself in changed conduct: ceasing evil, doing good, defending the powerless. Worship that leaves the orphan undefended and the widow unheard is worship God will not accept.
Gospel Focus
God has always looked past the ceremony to the heart and the hands. "To obey is better than sacrifice" (1 Samuel 15:22), and "Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world" (James 1:27). This does not diminish worship; it demands that worship be real, flowing from a clean life and issuing in justice and mercy. We cannot lift holy hands to God while wringing them over our neighbor. The washing God commands here He Himself provides in the next breath.
White as Snow (Isaiah 1:18)
In the middle of judgment, God holds out one of the most gracious offers in all Scripture.
Come Now, and Let Us Reason Together
"Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. If ye be willing and obedient, ye shall eat the good of the land: But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it. How is the faithful city become an harlot! it was full of judgment; righteousness lodged in it; but now murderers. Thy silver is become dross, thy wine mixed with water: Thy princes are rebellious, and companions of thieves: every one loveth gifts, and followeth after rewards: they judge not the fatherless, neither doth the cause of the widow come unto them. Therefore saith the Lord, the LORD of hosts, the mighty One of Israel, Ah, I will ease me of mine adversaries, and avenge me of mine enemies: And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin: And I will restore thy judges as at the first, and thy counsellors as at the beginning: afterward thou shalt be called, The city of righteousness, the faithful city. Zion shall be redeemed with judgment, and her converts with righteousness. And the destruction of the transgressors and of the sinners shall be together, and they that forsake the LORD shall be consumed. For they shall be ashamed of the oaks which ye have desired, and ye shall be confounded for the gardens that ye have chosen. For ye shall be as an oak whose leaf fadeth, and as a garden that hath no water. And the strong shall be as tow, and the maker of it as a spark, and they shall both burn together, and none shall quench them."
Hebrew Study
"Come now, and let us reason together" — the verb yakach is a legal term, to argue out a case and reach a settlement. The colors are chosen with care: "though your sins be as scarlet... though they be red like crimson" — the deep, double-dyed dyes of the ancient world that no washing could remove — "they shall be as white as snow... as wool." God names the most permanent stain He can, then promises to make it utterly, spotlessly clean.
Explanation
This is one of the tenderest invitations in all Scripture, and its setting makes it astonishing. God has just prosecuted His people as guilty rebels — and now, in the same breath, the offended Judge Himself proposes to settle the case not by sentencing but by cleansing. He does not minimize the sin; He calls it scarlet and crimson, indelible. Yet He offers to do what no human effort could — to turn the deepest, permanent stain snow-white. It is grace held out across a courtroom, the gospel in the mouth of the Judge, fulfilled at last in the blood that washes crimson sins white.
Gospel Focus
After the indictment comes an invitation no earthly judge would offer: "Come now, and let us reason together." The God who has every right to condemn instead pleads with the guilty to be reconciled. Scarlet and crimson were deep, fast dyes, colors that did not wash out; they picture sins too ingrained for us to remove. Yet God promises to make them "white as snow." Only God can do this. It points straight to the blood of Jesus, for "the blood of Jesus Christ his Son cleanseth us from all sin" (1 John 1:7), and "though your sins be as scarlet" finds its answer at the cross, where scarlet guilt is washed white. This is the heart of the gospel already beating in Isaiah's first chapter: God invites sinners to come and be made clean.
Chapter 1 in Review
Isaiah 1 opens the book with a courtroom scene. God calls heaven and earth to witness His charge against Judah: a people more thoughtless than the ox and donkey, going through the motions of religion while their hands are stained with injustice. God declares He is weary of sacrifices offered by unclean lives and calls instead for repentance shown in cleansed conduct and defended widows and orphans. Then, astonishingly, He extends mercy, inviting the guilty to reason with Him and offering to wash scarlet sins white as snow.
For the Apostolic reader, this chapter sets the tone for the whole gospel prophet. God is not fooled by outward worship; He wants clean hearts and just lives. Yet He does not leave us to cleanse ourselves. The washing He commands, He provides, pointing forward to the blood of Jesus that alone can make scarlet guilt white as snow. Judgment and grace meet in Isaiah 1, and grace has the last word: come now, and let us reason together.
- The root of sin is often thoughtlessness, failing to "consider" the God who made us.
- God rejects worship offered by unclean hands; true religion shows in justice and mercy (James 1:27).
- God pleads with sinners He could simply condemn: "Come now, and let us reason together."
- Only God can wash scarlet sins white, and He does it through the blood of Jesus (1 John 1:7).
Questions for Reflection
- God's first charge was that His people did not "consider" Him. Where has thoughtless drift crept into your walk with God?
- Is there any way your worship masks a life that needs to change in how you treat others?
- God offers to wash scarlet sins white as snow. Have you truly come to Him to be cleansed, or only performed religion?
