2 Chronicles 22:1-9

1Then the people of Jerusalem made Ahaziah, the youngest son of Jehoram, king in his place, since the raiders who had come into the camp with the Arabs1 had killed all the older sons. So Ahaziah son of Jehoram became king of Judah. 2Ahaziah was twenty-two2 years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, the granddaughter of Omri.

3Ahaziah also walked in the ways of the house of Ahab, for his mother was his counselor in wickedness. 4And he did evil in the sight of the LORD, as the house of Ahab had done, for to his destruction they were his counselors after the death of his father.

5Ahaziah also followed their counsel and went with Joram son of Ahab king of Israel to fight against Hazael king of Aram at Ramoth-gilead. But the Arameans3 wounded Joram.4 6So he returned to Jezreel to recover from the wounds they had inflicted on him at Ramah5 when he fought against Hazael king of Aram. Then Ahaziah6 son of Jehoram king of Judah went down to Jezreel to visit Joram son of Ahab, because Joram had been wounded.

7Ahaziah’s downfall came from God when he went to visit Joram. When Ahaziah arrived, he went out with Joram to meet Jehu son7 of Nimshi, whom the LORD had anointed to destroy the house of Ahab.

8So while Jehu was executing judgment on the house of Ahab, he found the rulers of Judah and the sons of Ahaziah’s brothers who were serving Ahaziah, and he killed them.

9Then Jehu looked for Ahaziah, and Jehu’s soldiers captured him while he was hiding in Samaria. So Ahaziah was brought to Jehu and put to death. They buried him, for they said, “He is the grandson of Jehoshaphat, who sought the LORD with all his heart.”

So no one was left from the house of Ahaziah with the strength to rule the kingdom.
