Jehoahaz in Easton's Bible Dictionary

Jehovah his sustainer, or he whom Jehovah holdeth. (1.) The youngest son of Jehoram, king of Judah (2 Chr. 21:17; 22:1, 6, 8, 9); usually Ahaziah (q.v.). (2.) The son and successor of Jehu, king of Israel (2 Kings 10:35). He reigned seventeen years, and followed the evil ways of the house of Jeroboam. The Syrians, under Hazael and Benhadad, prevailed over him, but were at length driven out of the land by his son Jehoash (13:1-9, 25). (3.) Josiah's third son, usually called Shallum (1 Chr. 3:15). He succeeded his father on the throne, and reigned over Judah for three months (2 Kings 23:31, 34). He fell into the idolatrous ways of his predecessors (23:32), was deposed by Pharaoh-Necho from the throne, and carried away prisoner into Egypt, where he died in captivity (23:33, 34; Jer. 22:10-12; 2 Chr. 36:1-4).
