As is the case with nearly all the books of “the prophets,” the book of Isaiah takes its name from its writer. Isaiah was married to a prophetess who bore him at least two sons (Isaiah 7:3; 8:3). He prophesied under the reign of four Judean kings—Uzziah, Jotham, Ahaz, and Hezekiah (1:1)—and he likely met his death under a fifth, the evil King Manasseh. Christian tradition as early as the second century identifies Isaiah as one of the prophets whose death is described in Hebrews 11:37, specifically the prophet who was “sawn in two.” Isaiah likely lived in Jerusalem, given the book’s concern with the city (Isaiah 1:1) and his close proximity to at least two significant kings during the period of his prophecy (7:3; 38:1).
