“The vision of Isaiah the son of Amoz, which he saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah.”
That is, a revelation or prophecy, which was one of the two means whereby God declared himself to his servants in old time, as Num. 12:6 , and therefore the Prophets were called Seers, 1 Sam. 9:9 . Isaiah was chiefly sent to Judah and Jerusalem, but not only: for in this book are prophecies concerning other nations also. Called also Azariah, 2 Kings 15:1 , of these Kings, read 2 Kings 14-21 , and 2 Chron. 25-33 .
