the prophet, son of Amoz. The Hebrew name signifies Salvation of Jahu (a shortened form of Jehovah). He prophesied concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah (Isaiah 1:1). He was married and had two sons. Rabbinical tradition says that Isaiah, when 90 years old, was sawn asunder in the trunk of a carob tree by order of Manasseh, to which it is supposed that reference is made in Hebrews 11:37.
