In the twelfth year of Joram the son of Ahab king of Israel did Ahaziah the son of Jehoram king of Judah begin to reign.
2 Kings 8:16
And in the fifth year of Joram son of Ahab king of Israel -- and Jehoshaphat [is] king of Judah -- hath Jehoram son of Jehoshaphat king of Judah reigned;
A son of thirty and two [years] was he in his reigning, and eight years he hath reigned in Jerusalem, and he goeth without desire, and they bury him in the city of David, and not in the graves of the kings.
