Isaiah

A prophet in Jerusalem tells a rich, religious nation that God is sick of its worship because it crushes the poor. Then the book turns to comfort: a suffering servant, a way home, and a new heaven and a new earth.

The big idea

In short: worship without justice is noise. God says, “I delight not in the blood of bullocks” (1:11). Instead: “seek judgment, relieve the oppressed, judge the fatherless, plead for the widow” (1:17).

Isaiah is quoted in the New Testament more than any other prophet. It moves from warning, to comfort, to hope for the whole world.

Keep it: The whole community stays healthy.
Break it: Injustice spreads, and the Bible says nations fall for it.

17Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow. 18Come 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.Isaiah 1:17-18 · KJV

At a glance

What it is
A book of prophecy, mostly poetry. 66 chapters.
Who wrote it
Isaiah son of Amoz, who worked in Jerusalem about 740–700 BC (1:1). Most scholars think chapters 40–66 were added by later prophets in his tradition, because they speak to exiles in Babylon and name the Persian king Cyrus (44:28; 45:1). Traditional readers see one prophet foreseeing the future. debated
An old copy
The Great Isaiah Scroll, found among the Dead Sea Scrolls in 1947, is a complete copy from about 125 BC. It is very close to the text used today.
Why it matters
Jesus begins his work by reading Isaiah 61 (Luke 4:17–21). “Swords into plowshares” (2:4), “Here am I; send me” (6:8), and “a man of sorrows” (53:3) come from here.

What it says

1–12 · Warning. God calls the nation a people who pray with hands “full of blood” (1:15). Their festivals are a burden to him (1:13–14). But there is a way back: “though your sins be as scarlet, they shall be as white as snow” (1:18). Isaiah sees God in the temple. Angels call, “Holy, holy, holy” (6:3), and he answers, “Here am I; send me” (6:8). He promises a coming child, “The Prince of Peace” (9:6), and a king who will judge the poor fairly (11:4).

5, 10 · The sins named. “Woe unto them that join house to house, that lay field to field” until the poor have nowhere to live (5:8). Woe to those who “call evil good, and good evil” (5:20). Woe to lawmakers who write laws that rob widows and orphans (10:1–2).

13–39 · The nations, and a king’s crisis. Isaiah speaks against Babylon, Egypt, and others. Assyria surrounds Jerusalem, and King Hezekiah prays. The city is spared (36–37).

40–55 · Comfort. “Comfort ye, comfort ye my people” (40:1). God will bring the exiles home. Those who wait on God “shall mount up with wings as eagles” (40:31). A servant of God will be “a light to the Gentiles,” meaning all nations (49:6). The servant suffers for others: “he was wounded for our transgressions” (53:5).

56–66 · The true fast and a new world. God does not want a show of fasting. He wants people “to loose the bands of wickedness… to deal thy bread to the hungry” (58:6–7). Keep the Sabbath as “a delight” (58:13). God will make “new heavens and a new earth” (65:17).

6Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke? 7Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?Isaiah 58:6-7 · KJV
Go deeper
  • Original words. Mishpat (justice, “judgment”) and tsedaqah (righteousness) are paired again and again (5:7). In 5:7 Isaiah makes a pun: God looked for mishpat and found mishpach (bloodshed), for tsedaqah and heard tseʿaqah (a cry).
  • Structure. Scholars often divide it into three parts: 1–39 (Isaiah’s own time), 40–55 (exile in Babylon), and 56–66 (after the return). The name “the Holy One of Israel” runs through all three.
  • How the laws interlock. Law 4 and Law 1 are joined: you can’t honor God and crush the poor (1:11–17). Law 10 appears as the Sabbath “delight” (58:13), right after the call to feed the hungry. Law 11 is in the king who judges the poor fairly (11:4) and the servant who suffers instead of ruling by force (53).

Hard parts

“A virgin shall conceive” (7:14)

What it says Isaiah gives King Ahaz a sign: a young woman will have a son named Immanuel, and before the child is grown, the enemy kings will be gone (7:14–16).

The rule underneath God first. The sign tells a frightened king to trust God, not alliances.

What people added The Hebrew word almah means a young woman of age to marry. The Greek translation used parthenos, “virgin,” and Matthew 1:23 quotes that. Christians read it as pointing to Jesus’ birth. Jewish readers read it as a sign in Ahaz’s own time. Many Christians hold both. Churches and traditions have split; this page does not settle it.

Who is the suffering servant? (52:13–53:12)

What it says A servant is “despised and rejected,” suffers for others’ sins, and is then lifted up (53:3–12).

The rule underneath Power serves. The servant wins by suffering, not by force.

What people added The New Testament applies it to Jesus (Acts 8:32–35). Jewish tradition most often reads the servant as Israel, which Isaiah itself calls God’s servant (49:3). Some read it as the prophet. Churches and traditions have split; this page does not settle it.

“Lucifer” (14:12)

What it says “How art thou fallen from heaven, O Lucifer, son of the morning!” The poem is a “proverb against the king of Babylon” (14:4).

The rule underneath Power serves. A proud king who oppresses nations falls.

What people added “Lucifer” is Latin for “light-bringer,” the morning star. It came into English from the Latin Bible. Later Christian tradition made it a name for Satan. The Hebrew text is about a human king. This is a clear case of a later layer laid over the text.

“I make peace, and create evil” (45:7)

What it says God says, “I form the light, and create darkness: I make peace, and create evil” (45:7).

The rule underneath God first. There are not two gods, one good and one bad.

What people added The Hebrew word raʿ can mean disaster or trouble, not only moral evil, and most modern translations say “disaster.” Readers still debate how God relates to suffering.

Translation notes that change meaning

  • 9:6 “The mighty God.” Christians read this as a title for the Messiah. Jewish readers often read the names as a sentence about God, given to a royal child. debated

How it has been used: A bronze statue called “Let Us Beat Swords into Plowshares,” by Yevgeny Vuchetich, stands at the United Nations in New York. The Soviet Union gave it in 1959.

Where it leads

One thing to do

This week

The true fast

Isaiah says the fast God wants is to share your bread and bring the poor into your home (58:7). This week, skip one meal or one purchase. Give what it would have cost to feed someone, or invite someone who is alone to eat with you. Write in your journal who it was.

How to read it. Start with 1, 6, 40, 53, and 58. Then read 1–12 and 40–55 straight through.
