1. The son and successor of Jehu, reigned 17 years, B.C. 856-840, over Israel in Samaria. His inglorious history is given in 2Ki_13:1-9. Throughout his reign, 2Ki_13:22, he was kept in subjection by Hazael, king of Damascus. Jehoahaz maintained the idolatry of Jeroboam; but in the extremity of his humiliation, he besought Jehovah, and Jehovah gave Israel a deliverer -- probably either Jehoash, 2Ki_13:23 and 2Ki_13:25, or Jeroboam II, 2Ki_14:24-25.

2. Jehoahaz, otherwise called Shallum, son of Josiah, whom he succeeded as king of Judah. He was chosen by the people, in preference to his elder brother, compare 2Ki_23:31 and 2Ki_23:36, B.C. 610, and he reigned three months in Jerusalem. Pharaoh-necho sent to Jerusalem to depose him, and to fetch him to Riblah. There he was cast into chains, and from thence, he was taken into Egypt, where he died.

3. The name given, 2Ch_21:17, to Ahaziah, the youngest son of Jehoram, king of Judah.
