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).
So perhaps, for the same reason, jehoahaz was shortened into Ahaz.
Necho caused jehoahaz to be secured, and sent him as a prisoner to Egypt.
After his three months' campaign he sent for jehoahaz to Riblah, and the unhappy prince had no choice but to obey.
And Necho took jehoahaz his brother, and carried him to Egypt.
Jehu's son, jehoahaz, witnessed the deepest humiliation of Israel at the hands of Syria.
The people of the land made Josiah's son Shallum king, under the name of jehoahaz.
His son jehoahaz continued in gross idolatry (2 Kings 13:2-9).
But the defeat and death of Josiah and the deposition of jehoahaz followed to discredit Jeremiah and his friends.
And the people of the land took jehoahaz the son of Josiah, and anointed him, and made him king in his father's stead.
Passing by the two elder sons of Josiah, the people raised to the throne the third son, jehoahaz.
