2 Kings 1:17-18
1:17 He died just as the Lord had prophesied through Elijah. In the second year of the reign of King Jehoram son of Jehoshaphat over Judah, Ahaziah’s brother Jehoram replaced him as king of Israel, because he had no son.
1:18 The rest of the events of Ahaziah’s reign, including his accomplishments, are recorded in the scroll called the Annals of the Kings of Israel.
