2 Kings 8:25-27

25In the twelfth year of the reign of Joram son of Ahab over Israel, Ahaziah son of Jehoram became king of Judah. 26Ahaziah was twenty-two years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, the granddaughter of Omri king of Israel.

27And Ahaziah walked in the ways of the house of Ahab and did evil in the sight of the LORD like the house of Ahab, for he was a son-in-law of the house of Ahab.
