II Kings 8:18, 26-27

And he walked in the way of the kings of Israel, just as the house of Ahab had done, for the daughter of Ahab was his wife; and 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. And he walked in the way of the house of Ahab, and did evil in the sight of the LORD, like the house of Ahab, for he was the son-in-law of the house of Ahab.
