(2 Kings 8:17-18, New American Bible)
He [Ahaziah] was twenty-two years old when he began his reign, and he reigned one year in Jerusalem. His mother's name was Athaliah; she was the daughter of Omri, king of Israel. He conducted himself like the house of Ahab, doing evil in the Lord's sight as they did, since he was related to them by marriage.
