“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.
