2 Chronicles 22:1-3

King James Version

22 And the inhabitants of Jerusalem made Ahaziah his youngest son king in his stead: for the band of men that came with the Arabians to the camp had slain all the eldest. So Ahaziah the son of Jehoram king of Judah reigned.

² Forty and two years old was Ahaziah when he began to reign, and he reigned one year in Jerusalem. His mother's name also was Athaliah the daughter of Omri.

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