Isaiah is considered the greatest prophet of all time, foretelling much about Jesus 700 years later. Isaiah was a witness to the people of Jerusalem during the reign of King Uzziah to that of King Hezekiah, who both ruled over Judah.
- "The prophecies of Isaiah son of Amoz, who prophesied concerning Judah and Jerusalem in the reigns of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah." (Isaiah 1:1)
Isaiah lived in Judah, the southern kingdom of the divided nation of Israel. He was a prophet to four kings of Judah from about 740 B.C. to 681 B.C., but he preached repentance and salvation to the whole nation. Although it is not recorded in the Bible, tradition states that Isaiah met his end by being sawed in half inside a log during the reign of the evil king Manasseh.
Isaiah's prophecies are collected in the Biblical book of Isaiah.
