2 Chronicles 22:1-3

11Then the inhabitants of Jerusalem made 2Ahaziah, his youngest son, king in his place, for the band of men who came with 3the Arabs to the camp had slain all the older sons. So Ahaziah the son of Jehoram king of Judah began to reign.

2Ahaziah was 4twenty-two years old when he became king, and he reigned one year in Jerusalem. And his mother’s name was Athaliah, the 5granddaughter of Omri.

3He also walked in the ways of the house of Ahab, for his mother was his counselor to do wickedly.
