2 Chronicles 22:1-2

Darby Translation

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

² Ahaziah was twenty-two years old when he began to reign; and he reigned one year in Jerusalem; and his mother's name was Athaliah, daughter of Omri.
