Isaiah 1

Isaiah opens with God’s courtroom charge against His own people. They are sinful, sick and ruined, and their worship is empty because their lives are unjust. Yet God offers cleansing, promises to refine Jerusalem, and warns that those who persist in rebellion will perish.

Isaiah 1:1

The book opens by naming the prophet, his father, and four kings of Judah. Isaiah’s message is a vision, something God showed him, concerning Judah and Jerusalem. His own name means that the LORD saves, and that hope runs through the whole book.

BSA: vision (“a prophetic revelation, divine insight”): What follows is not Isaiah’s opinion but something God opened to his sight.

See also: 2 Kings 15:1-7.

Isaiah 1:2

God summons heaven and earth as witnesses, as in a trial. The charge is painful: He raised His people like children, and they turned on Him. Rebellion here is not a mere mistake but a family betrayal by those He nurtured.

BSA: Listen (“hear and obey”): God asks for more than hearing; He expects a response. rebelled (“transgressed, revolted”): The word suggests breaking away from rightful authority.

See also: Deuteronomy 32:1.

Isaiah 1:3

Farm animals know who feeds them and where they are fed. God’s people do not. The ox and donkey are humble, yet wiser than Israel, who has forgotten the One who provides everything.

BSA: know (“is ignorant of, lacks understanding”): Israel’s problem is not lack of information but a failure to recognize and trust her Master.

Isaiah 1:4

Isaiah cries out over the nation’s condition. Sin is pictured as a heavy load, and the people as a family line of wrongdoing. The root problem is relational: they have abandoned the LORD, scorned the Holy One, and walked away from Him.

BSA: turned their backs (“gone away backward, become strangers”): They have not just drifted; they have become estranged from the God who is theirs.

Hebrew: קְדוֹשׁ (qedosh, H6918) — “holy, set apart.” God is utterly distinct and pure. To despise Him is to spurn the standard of all goodness, which is why the title ‘Holy One of Israel’ marks the whole book.

See also: Isaiah 6:3.

Isaiah 1:5-6

Sin is described as a body sick from head to foot. Discipline has already fallen, yet the people keep rebelling. The wounds are untreated: not cleaned, bandaged or soothed. Sin damages the whole person, and the nation has refused any remedy.

BSA: soothed (“mollified, comforted”): Oil would have eased the pain, but no one has tended the wounds. heart (“innermost being, emotions”): The sickness reaches deeper than the body, to the center of the person.

Isaiah 1:7-8

The picture turns from a wounded body to a ravaged land. Cities burn and foreign invaders eat the harvest. Jerusalem stands alone, like a flimsy watchman’s hut left in a field after the crop is gathered. These are the results of turning from God.

BSA: shelter (“a small booth, a temporary dwelling”): Jerusalem looks fragile and temporary, easily blown away.

Isaiah 1:9

Only God’s mercy kept the nation from being wiped out like Sodom and Gomorrah. A small remnant survived. This idea of a preserved remnant becomes a major hope in Isaiah. Survival itself is a gift of grace.

BSA: survivors (“remnant, those who remain alive”): God keeps a faithful few as the seed of a future.

See also: Romans 9:29; Genesis 19:24-25.

Isaiah 1:10

Isaiah shocks his hearers by calling Jerusalem’s leaders rulers of Sodom and Gomorrah. They thought themselves righteous because of their religion. God’s word is still addressed to them, and they are told to listen.

BSA: instruction (“law, teachings”): God’s word is His guiding teaching, meant to shape how His people live.

Isaiah 1:11-12

God is not asking for more sacrifices. He has had more than enough, and without a sincere heart the offerings give Him no pleasure. Their temple visits had become a mere trampling of His courts. He never asked for worship that was only ritual.

BSA: trampling (“treading down, stomping on”): Crowds tread through the courts, but without reverence it is mere noise and movement.

See also: 1 Samuel 15:22; Psalm 50:8-13.

Isaiah 1:13-14

Incense, festivals, Sabbaths and monthly feasts were all commanded by God, yet now He hates them. The problem is not the practices but pairing them with wickedness. God says He cannot bear worship mixed with injustice. He is weary, as though carrying a load.

BSA: burden (“trouble, weight”): Their religion has become something heavy God is tired of carrying. iniquity (“evil, wickedness”): Sin hidden under holy ceremony spoils the whole gathering.

See also: Amos 5:21-24.

Isaiah 1:15

Lifting open hands was a normal posture of prayer. But God says He will turn His eyes away. Hands stained with violence and the blood of the innocent cannot be raised to Him with a clear conscience. Many prayers do not make up for a hardened life.

BSA: hide (“conceal, turn away”): God deliberately looks elsewhere, which is a sign of serious displeasure.

See also: Psalm 66:18; Proverbs 28:9.

Isaiah 1:16-17

God now gives a way back: wash, stop evil, learn to do good. The cure is practical. Seek justice, rescue the oppressed, and stand up for orphans and widows, the people with no one to speak for them. True repentance shows itself in how we treat the weak.

BSA: Defend (“vindicate, support”): God asks His people to take the side of the helpless and see them treated fairly.

Hebrew: רָחַץ (rachats, H7364) — “wash.” This is the word for washing the body with water. God asks for visible cleansing, an outward change that matches an inward one.

See also: James 1:27.

Isaiah 1:18

God invites His people to a reasoning-together, like a fair hearing. Sins as deep as scarlet dye, which does not wash out, can be made white as snow. The invitation shows God’s astonishing readiness to forgive those who come.

BSA: scarlet (“deep red, crimson”): Scarlet was a colorfast dye, picturing sin that cannot be removed by human effort.

See also: Psalm 51:7; 1 John 1:9.

Isaiah 1:19-20

The choice is set before them plainly. Willing obedience brings the good of the land, while stubborn rebellion brings the sword. God’s blessing is not an automatic right. The closing line reminds them that these are His own words.

BSA: willing (“to give ear to my word”): Real willingness means being ready to listen and respond to God.

See also: Deuteronomy 30:15-19.

Isaiah 1:21

Jerusalem is pictured as a wife who has become unfaithful. She was once the faithful city, where justice and righteousness lived, but violence has replaced them. Faithlessness to God and corruption in society go together.

BSA: harlot (“fornicator, idolatrous”): Turning from God to other loyalties is spiritual adultery.

See also: Hosea 2:2.

Isaiah 1:22-23

What was precious has been spoiled: silver turned to scrap, wine watered down. The rulers love bribes and ignore the orphan and widow. Corrupt leaders cheat the vulnerable, and the city’s worth has been quietly drained away.

BSA: dross (“waste, impurities”): Dross is the useless waste that rises when metal is melted, showing how worthless the city has become. bribes (“gifts, rewards”): Leaders accept payments that twist justice in favor of the rich.

Isaiah 1:24

God announces judgment against the powerful and the corrupt. The titles piled up here stress His might: He commands every army and no one can stand against Him. His anger is that of a wronged ruler who must set things right.

BSA: Mighty One (“emphasizing power”): The title underlines that the God who judges has all strength.

Isaiah 1:25

God’s judgment is also a refining. Like a smelter melting silver to skim off the waste, He will remove the impurities. The fire is painful but its purpose is to leave Jerusalem pure, not destroyed.

BSA: purge (“refine, cleanse”): The word is from smelting, where heat separates the pure from the worthless.

See also: Malachi 3:2-3.

Isaiah 1:26

After the cleansing, God promises good leaders as in the best days of the past. Jerusalem will again deserve its names: the City of Righteousness, the Faithful City. His discipline is aimed at restoring what He first intended.

BSA: restore (“give back, return to a former state”): God does not merely punish; He brings back what was lost.

Isaiah 1:27-28

Zion’s rescue comes through God’s justice and righteousness, and those who turn back are redeemed. But those who stay in rebellion and abandon the LORD will perish. The same God who redeems also judges, and the dividing line is repentance.

BSA: redeemed (“rescued, ransomed”): The word suggests buying someone back at a cost, a rescue God himself provides. repentant ones (“those who return, convert”): Those who turn around are the ones who share in Zion’s rescue.

See also: Isaiah 59:20.

Isaiah 1:29-30

The people’s pleasure in sacred trees and gardens, places of idol worship, will turn to shame. Those who trusted in them will be like a withered oak and a waterless garden. What they relied on cannot sustain them, and they will share its decay.

BSA: sacred oaks (“trees of your desire, idols”): These were worship sites tied to idols that people had chosen over the LORD.

See also: Jeremiah 17:5-6.

Isaiah 1:31

The strong man and his work will burn together like dry tinder lit by a spark, and no one will put it out. Human might and achievement, when set against God, are as flammable as straw. Only trust in Him lasts.

BSA: tinder (“like tow, refuse of flax”): Tow is rough, dry flax waste that catches fire instantly, showing how quickly human power can be consumed.
