During the thirty-seventh year of the reign of King Joash of Judah, Jehoahaz's son Jehoash began a sixteen year reign as king over Israel in Samaria.

Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem. He did not do what was right in the sight of the Lord his God, as his father (ancestor) David had done.
