2 Kings 8:18, 26-27

He walked in the ways of the kings of Israel, just as the house of Ahab had done, for [Athaliah] the daughter of Ahab became his wife. He did evil in the sight of the LORD.

Ahaziah was twenty-two years old when he became king, and he reigned one year in Jerusalem. His mother’s name was Athaliah, the granddaughter of Omri king of Israel. He walked in the ways of the house of Ahab and did evil in the sight of the LORD, as did the house of Ahab, for he was a son-in-law of the house of Ahab.
