Isaiah prophesied in the days of the last four kings of Judah. They were Uzziah, Jotham, Ahaz, and Hezekiah.
Isaiah received his commission to ministry in a frightening vision. This was in the last year of king Uzziah, Hezekiah’s great grandfather (Isaiah 6:1-10).

Isaiah’s second son was named Maher-shalal-hash-baz, meaning "Swift to the booty, speedy to the prey" (Isaiah 8:1-4). The little boy’s birth and name was a sign to Ahaz that the king of Assyria was coming swift to the booty and speedy to the prey (Isaiah 10:5-7,2Chr 28:19-22).
Isaiah helped to prevent Judah’s captivity and exile by Assyria when the Assyrian king Sennacherib invaded the land during Hezekiah’s reign.
