ISAIAH

Isaiah was a major Hebrew prophet who lived and prophesied in the 8th century BCE, during a turbulent time in Judah’s history marked by political upheaval, moral decay, and the looming threat of foreign invasion. He served during the reigns of Kings Uzziah, Jotham, Ahaz, and Hezekiah (c. 740–700 BCE), providing both stern warnings of judgment and profound visions of hope. Isaiah is said to have been executed by King Manasseh for heretical speech.

Isaiah is best known for calling the people of Judah to repentance and for his powerful visions of God’s holiness and justice. At the same time, he offered messages of consolation, emphasizing God’s redemptive plan and the coming of a righteous ruler, often interpreted in Christian theology as prophetic references to Jesus Christ.

Isaiah is revered as a prophet in each Abrahamic religion. Crucially, the Book of Isaiah is the first Hebrew text to affirm monotheism, serving as a model for the following Abrahamic traditions. Unlike prophets such as Amos and Micah, Isaiah emphasizes the righteousness of God instead of Israel’s covenant. Isaiah 2:3–4 has often been used by pacifists, anti-war activists, and diplomats, signifying the book’s influence on Christian and Western culture.
