II Kings 8:16, 24

Now in the fifth year of Joram the son of Ahab, king of Israel, Jehoshaphat having been king of Judah, Jehoram the son of Jehoshaphat began to reign as king of Judah.

So Joram rested with his fathers, and was buried with his fathers in the City of David. Then Ahaziah his son reigned in his place.
