Biblical scholars are generally agreed that 66 chapters of the Book of Isaiah contain the words of two, or perhaps even three, different prophets: First Isaiah, who prophesied between, 742–701 B.C.E. in Jerusalem; Second Isaiah, who prophesied in about 540 B.C.E. during the Babylonian Exile; and perhaps a Third Isaiah who prophesied in Jerusalem after the return from Exile in 538 B.C.E.
