2 Kings 9:28

To Jerusalem. Jehu permitted the body of the king of Judah to be taken back to the king’s own capital for burial. It was not the Lord’s purpose that the nation of Judah should be associated with its northern neighbor in close alliance. Jehoshaphat was rebuked by the prophet for giving his assistance to Ahab against Benhadad (2 Chronicles 19:2). The conduct of Ahaziah in assisting Joram in war against Hazael was also reprehensible in the eyes of God (2 Chronicles 22:4, 5). For such assistance Ahaziah paid with his life.

With his fathers. Under usual circumstances the wicked king Ahaziah would probably not have been given burial in the sepulchers of the kings in the City of David. This honor was accorded him, despite his connection with the house of Ahab, because of his descent from the good king Jehoshaphat, “because, said they, he is the son of Jehoshaphat, who sought the Lord with all his heart” (2 Chronicles 22:9).
