When and where did the prophet Isaiah write?

Answer 1

A careful study of the Book of Isaiah reveals that it actually had three main authors: the prophet Isaiah, son of Amoz, who wrote from Jerusalem in the late eighth and early seventh centuries BCE, during the reigns of Kings Uzziah, Jotham, Ahaz and Hezekiah of Judah; an anonymous author now known as Second Isaiah, who lived during the Babylonian Exile; and another anonymous author, now known as Third Isaiah, who lived shortly after the Babylonian Exile. Each of the three prophets had a very different and distinctive literary style and wrote of different eras.

Answer 2

The Bible book of Isaiah was written in Jerusalem sometime after 732 BCE. The time period that his writing covered was during 778 to after 732 BCE.
