Meaning: Jehovah his sustainer, or he whom Jehovah holdeth
This was the name of three biblical kings.
King Jehoahaz (aka Ahaziah), the youngest son of King Jehoram of Judah (2 Chronicles 21:17; 22:1, 6, 8-9); usually Ahaziah.
King Jehoahaz of Israel—the son and successor of King Jehu 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).
King Jehoahaz (Shallum) of Judah—Josiah's third son, usually called Shallum (1 Chronicles 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; Jeremiah 22:10-12; 2 Chronicles 36:1-4).
