Page "Isaiah" Paragraph 4

It is stated in the first verse of the Book of Isaiah that he prophesied during the reigns of Uzziah ( or Azariah ), Jotham, Ahaz, and Hezekiah, the kings of Judah ().

Uzziah reigned fifty-two years in the middle of the 8th century BC, and Isaiah must have begun his ministry a few years before Uzziah's death, probably in the 740s BC.

Isaiah lived until the fourteenth year of Hezekiah ( who died 698 BC ), and may have been contemporary for some years with Manasseh.

Thus Isaiah may have prophesied for as long as sixty-four years.
