2 Kings 8:16, 24

In the fifth year of Joram the son of Ahab, king of Israel, when Jehoshaphat was king of Judah, Jehoram the son of Jehoshaphat, king of Judah, began to reign.

So Joram slept with his fathers and was buried with his fathers in the city of David, and Ahaziah his son reigned in his place.
