When, and by Whom, Was the Book of Isaiah Written?
“The vision which Isaiah, son of Amos, saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz and Hezekiah, kings of Judah”—Isaiah 1:1 NAB
Until about the last 250 years, the book of Isaiah was generally accepted by Christians as being written entirely by the prophet Isaiah in the latter part of the 8th century BCE. Nowadays, however, many “scholars” think the book was written by various writers over the course of several centuries, citing factors such as differences in subject matter, style, theology, vocabulary, and the viewpoint that predictive prophesy is impossible. The real reason for this is, however, that they don’t think predictive prophecy is possible. While there are a variety of views about the writership of Isaiah, critics often claim that chapters 40-66 were not written by “Isaiah, son of Amos.” However, careful examination of the book reveals that chapters 36-39 are a historical interlude that concludes the first section of the book, chapters 1-35, and introduces the last section, chapters 40-66. This reveals the unity of the entire book.
