Isaiah #23

Isaiah ministered in Jerusalem through the reigns of four kings, warning Judah of judgment while unfolding, more clearly than any other Old Testament prophet, the hope of a coming Servant-King who would suffer for his people’s sin and reign in everlasting peace.

Author and Date

Tradition attributes the whole book to the prophet Isaiah son of Amoz, who served under Uzziah, Jotham, Ahaz, and Hezekiah (Isaiah 1:1); his call came c. 740 BC, the year of Uzziah’s death (Isaiah 6:1). Many scholars propose that chapters 40-66, which address exiles in Babylon and name Cyrus, come from a later author or authors; others defend single authorship, citing the book’s literary unity and the possibility of predictive prophecy. The question remains disputed.

Background and Audience

Isaiah spoke to Judah and Jerusalem during Assyria’s rise. The northern kingdom fell in 722 BC, and Sennacherib’s army threatened Jerusalem in 701 BC. Later chapters look ahead to Babylon’s conquest and the exile, addressing a people in need of comfort and the assurance of return.

Key Verses

• Isaiah 6:1-8 — Isaiah’s vision of the LORD enthroned and his commissioning as prophet
• Isaiah 7:14 — the sign of Immanuel given to Ahaz, applied by Matthew to Jesus
• Isaiah 9:6-7 — a promised child-king whose government and peace never end

How It Fits the Bible

Isaiah opens the Major Prophets and is among the Old Testament books most often quoted in the New. Jesus read from Isaiah in the Nazareth synagogue (Luke 4:17-21), and the Gospel writers, notably Matthew, draw on it repeatedly. Its contemporary Micah shares its themes, and Jeremiah follows it.
