1Then the people of Jerusalem made Ahaziah, the youngest son of Jehoram, king in his place, since the raiders who had come into the camp with the Arabs had killed all the older sons. So Ahaziah son of Jehoram became king of Judah.
2Ahaziah was twenty-two years old when he became king, and he reigned in Jerusalem one year. His mother’s name was Athaliah, the granddaughter of Omri.
