2 Kings 8:18, 26-27

And he walked in the way of the kings of Israel, as the house of Ahab had done, for the daughter of Ahab was his wife. And he did what was evil in the sight of the LORD.

Ahaziah was twenty-two years old when he began to reign, and he reigned one year in Jerusalem. His mother’s name was Athaliah; she was a granddaughter of Omri king of Israel. He also walked in the way of the house of Ahab and did what was evil in the sight of the LORD, as the house of Ahab had done, for he was son-in-law to the house of Ahab.
