The Book of Isaiah

The Book of Isaiah is the 23rd book of the Bible. It was written around the 8th century BCE, during a time of great turmoil in the ancient Near East. The name of the book comes from its author, Isaiah, a prophet whose name means "Yahweh is salvation." The prophet Isaiah is a central figure throughout the text, and he interacts with various kings of Judah, including Uzziah, Jotham, Ahaz, and Hezekiah. Isaiah lived and preached in Jerusalem, and his prophecies often address the events and issues of his day, such as the threat of the Assyrian Empire and the apostasy of the people of Judah. Notable parts of the book include the call of Isaiah (Isaiah 6), the Immanuel prophecy (Isaiah 7), and the suffering servant passages (Isaiah 52-53).

Background of Isaiah

The Book of Isaiah covers a wide range of themes, including judgment and salvation, idolatry and true worship, the holiness of God, and the importance of relying on God rather than human power or alliances. The book was written to call the people of Judah back to faithfulness and to provide comfort and hope for those facing exile and suffering. It is widely respected for its prophetic insights, poetic beauty, and theological depth. At the time of the Book of Isaiah’s writing, there was a period of great political upheaval and spiritual decline in the kingdoms of Israel and Judah. Isaiah’s prophecies were a call to repentance and a reminder of God’s sovereign control over world events.

Isaiah’s Prophecies about the Messiah

One of the most significant aspects of the Book of Isaiah is its collection of prophecies concerning the Messiah. These prophecies are considered by Christians to be key Old Testament predictions of the coming of Jesus Christ.

  1. Immanuel – God With Us (Isaiah 7:14)
    In a prophecy delivered to King Ahaz, Isaiah speaks of a virgin who will conceive and give birth to a son named Immanuel, which means God with us. This verse is interpreted by Christians as a prophecy of the virgin birth of Jesus. The Gospel of Matthew directly cites this prophecy in the context of Jesus’ birth (Matthew 1:23).

  2. Prince of Peace (Isaiah 9:6-7)
    This prophecy announces the birth of a child who will be called Wonderful Counselor, Mighty God, Everlasting Father, and Prince of Peace. His reign will bring endless peace and justice, upholding it with righteousness from that time on and forever. The Christian tradition interprets this prophecy as speaking about Jesus, with his divine titles and the nature of his peaceful and just kingdom reflecting the mission and divinity of Christ.

  3. The Root of Jesse (Isaiah 11:1-10)
    This prophecy describes a righteous ruler who will come from the line of Jesse (King David’s father), filled with the Spirit of God, who will judge with righteousness and strike the earth with the rod of his mouth. This messianic figure is depicted as a bringer of peace, under whom even natural predators and prey will live together harmoniously. In the New Testament, the Apostle Paul directly quotes from this passage in reference to Jesus (Romans 15:12).

  4. The Cornerstone (Isaiah 28:16)
    Isaiah 28:16 portrays the Sovereign Lord declaring: So this is what the Sovereign Lord says: ‘See, I lay a stone in Zion, a tested stone, a precious cornerstone for a sure foundation; the one who relies on it will never be stricken with panic.’ The image of a cornerstone is one of stability and reliability. In the New Testament, Apostle Peter applies this prophecy directly to Jesus (1 Peter 2:6), presenting Him as the cornerstone of the spiritual edifice of the Church. The notion of the cornerstone as a tested and precious stone aligns with the Christian understanding of Christ as a firm foundation upon whom faith is securely built. Those who rely on this cornerstone, i.e., place their faith in Christ, will find a sure foundation that offers peace and eliminates fear.

  5. The Righteous King (Isaiah 32:1)
    In Isaiah 32:1, the prophecy foretells of a king who will reign in righteousness and rulers who will rule with justice: See, a king will reign in righteousness and rulers will rule with justice. While this verse does not explicitly mention a Messiah, it is often seen in a messianic context within Christian interpretation, pointing to the righteous rule of Christ. This rule embodies the ethical character of the kingdom of God that Jesus proclaimed, establishing a reign of righteousness and justice.

  6. The Suffering Servant (Isaiah 52:13-53:12)
    Perhaps one of the most poignant and powerful of Isaiah’s messianic prophecies, the Suffering Servant passage describes a servant of God who will suffer on behalf of others, bearing their iniquities and bringing them peace. He is described as being despised and rejected, a man of suffering and familiar with pain.

    The servant willingly submits to suffering, like a lamb led to the slaughter, and his suffering results in justification for many. This prophecy is interpreted by Christians as a clear foreshadowing of the suffering, death, and resurrection of Jesus Christ. The New Testament frequently cites this passage in relation to Jesus’ sacrificial death on the cross (e.g., Acts 8:32-35; 1 Peter 2:22-25).

  7. The Anointed Preacher (Isaiah 61:1-3)
    This passage describes an individual anointed by God to bring good news to the poor, bind up the brokenhearted, proclaim liberty to the captives, and release from darkness for the prisoners. He is also to proclaim the year of the Lord’s favor, and comfort all who mourn. Jesus himself reads this passage in the synagogue in Nazareth and applies it to his own ministry, declaring, Today this scripture is fulfilled in your hearing (Luke 4:16-21).

  8. The Light to the Nations (Isaiah 42:1-7, 49:6)
    In these passages, the servant of the Lord is described not only as a covenant for the people of Israel but also as a light for the Gentiles (non-Jewish nations), showing God’s intent for salvation to reach all nations. These verses are also used in reference to Jesus in the New Testament (Acts 13:47).

Additional Notes

Extrabiblical Support for Isaiah

The Book of Isaiah is one of the best-attested books of the Bible in terms of archaeological and textual evidence. The Dead Sea Scrolls, for example, include a complete copy of the Book of Isaiah from the 2nd century BCE. This text closely matches the version of Isaiah found in modern Bibles, demonstrating the remarkable accuracy of the biblical text over centuries. In terms of archaeological evidence, the Assyrian annals provide a historical context that aligns with the events and circumstances described in Isaiah. The Sennacherib Prism, for instance, corroborates the Assyrian invasion of Judah as depicted in Isaiah 36-37.
