Isaiah was one of the major prophets of ancient Israel. Isaiah is Hebrew for "God is salvation." Isaiah is one of the longest prophetic books (66 chapters). Originating in the 8th century BCE, it was updated at least twice, in the 7th and 6th centuries BCE (the Babylonian and Persian periods) and perhaps the Hellenistic period (4th to 1st centuries BCE). Scholars sometimes referred to the sections as Proto-Isaiah (Chapters 1-39), Deutero-Isaiah (40-55), and Trito-Isaiah (56-66).
