II Chronicles 22:7

Ahaziah beans to reign; and reigns wickedly under the counsels of his bad mother, Ch2 22:1-4. He is slain by Jehu, who destroys all the house of Ahab, Ch2 22:5-9. Athaliah destroys all the seed royal of Judah, except Joash, who is hidden by his nurse in the temple six years, Ch2 22:10-12.

AHAZIAH SUCCEEDING JEHORAM, REIGNS WICKEDLY. (Ch2 22:1-9) the inhabitants of Jerusalem made Ahaziah . . . king--or Jehoahaz (Ch2 21:17). All his older brothers having been slaughtered by the Arab marauders, the throne of Judah rightfully belonged to him as the only legitimate heir.

And it came to pass, that when Jehu was executing judgment on the house of Ahab,.... On Joram, his son, and seventy more sons, his kinsfolks, courtiers, and priests: and found the princes of Judah, and or even the sons of the brethren of Ahaziah; whose number was forty two: that ministered to Ahaziah; had offices in his court, or in obedience to his will, went to visit the children of the king and queen of Israel: and he slew them; Jehu did; of the occasion, time, and place of his meeting with them, and slaying them, see Kg2 10:12.

We read, in the foregoing chapter, of the carrying away of Jehoram's sons and his wives; but here we find one of his sons and one of his wives left, his son Ahaziah and his wife Athaliah, both reserved to be the shame and plague of his family. I. Ahaziah was the shame of it as a partaker, 1. In the sin, and, 2. In the destruction, of the house of Ahab (Ch2 22:1-9). II. Athaliah was the plague of it, for she destroyed all the seed-royal, and usurped the throne (Ch2 22:10-12).

22:7-9 The death of Ahaziah was a punishment for his alliance with the king of Israel. The Judahite king who lived by the counsel of the Israelite house of Omri shared their fate and found no refuge there at the time of his death. Ahaziah’s infidelity brought David’s line almost to the same point as Saul’s line, with no one left to assume the throne.
