"And Joram [Jehoram] king of Israel and Ahaziah king of Judah went out, each in his chariot ... against Jehu" (2 Kings ix, 21), "And Jehu drew a bow with his full strength, and smote Jehoram between his arms, and the arrow went out at his heart" (24). "But when Ahaziah the king of Judah saw this he fled by way of the garden house. And Jehu followed after him, and said, Smite him also in the chariot. And they did so" (27). Jehoram, king of Israel, and Ahaziah, king of Judah, were thus slain at the same time. Jehu succeeded Jehoram; Athaliah succeeded Ahaziah, reigned six years, and was in turn succeeded by Joash. Jehu had thus reigned six years over Israel when Joash became king of Judah. As Jehoram reigned twelve years, from the death of Ahaziah [of Israel] to the accession of Joash then, was eighteen years. From the death of Jehoshaphat to the accession of Joash, Judah's sovereigns reigned as follows: Joram 8 years, Ahaziah 1 year, Athaliah 6 years--a total of fifteen years. If from the death of Ahaziah to the reign of Joash was eighteen years, and from the death of Jehoshaphat to the reign of Joash was fifteen years, Jehoshaphat therefore died three years after Ahaziah died. 7. "In the second year of Joash son of Jehoahaz king of Israel reigned Amaziah the son of Joash king of Judah" (2 Kings xiv, 1). From the death of Ahaziah to the accession of Amaziah the reigns of Israel's kings were: Jehoram 12 years, Jehu 28 years, Jehoahaz 17 years, Joash 2 years. 12 years + 28 years + 17 years + 2 years = 59 years. From the death of Jehoshaphat to the accession of Amaziah, Judah's kings reigned--Joram 8 years, Ahaziah 1 year, Athaliah 6 years, Joash 40 years. 8 years + 1 year + 6 years + 40 years = 55 years. If from the death of Ahaziah to the accession of Amaziah was fifty-nine years, and from the death of Jehoshaphat to the accession of Amaziah was fifty-five years, Jehoshaphat therefore died four years after Ahaziah died. 8. "And Jehoshaphat the son of Asa began to reign over Judah in the fourth year of Ahab king of Israel" (1 Kings xxii, 41). If Ahab reigned twenty-two years and Jehoshaphat began to reign in the fourth year of Ahab's reign, Jehoshaphat had reigned eighteen years when Ahab died, and twenty years when Ahaziah died. As Jehoshaphat reigned twenty-five years, he therefore died five years after Ahaziah died. 9. "Ahaziah the son of Ahab began to reign over Israel in Samaria the seventeenth year of Jehoshaphat king of Judah, and reigned two years over Israel" (1 Kings, xxii, 51). If Ahaziah began to reign in the seventeenth year of Jehoshaphat and reigned two years before he died, he died in the nineteenth year of Jehoshaphat's reign. As Jehoshaphat reigned twenty-five years, he therefore died six years after Ahaziah died. 10. "Now Jehoram the son of Ahab began to reign over Israel in Samaria in the eighteenth year of Jehoshaphat king of Judah" (2 Kings iii, 1).
