2 Kings 19:2

Isaiah is here for the first time introduced into the history. His own writings show us how active a part he had taken in it for many years previously. This was the fourth reign since he began his prophesyings; and during two reigns at least, those of Ahaz and Hezekiah, he had been a familiar counselor of the monarch. He had probably counseled the revolt from Assyria, and had encouraged the king and people to persevere in their resistance. The exact date of prophecies can seldom be fixed with any certainty; but we can scarcely he mistaken in regarding 2 Kings 10; 30; 31 as written about the time of Hezekiah’s second revolt.
