1 Kings 22:2

And it came to pass in the third year [Of the peace; not after the death of Naboth, as Stanley], that Jehoshaphat the king of Judah came down [The journey to Jerusalem being invariably described as a "going up," one from Jerusalem to the provinces would naturally be spoken of as a "going down"] to the king of Israel. [For aught that appears, this was the first time that the monarchs of the sister kingdoms had met, except in battle, since the disruption, though the marriage of Jehoram, son of Jehoshaphat, with Athaliah, the daughter of Ahab and Jezebel, had taken place some years before this date ( 2 Chronicles 18:1 , 2 Chronicles 18:2 ). It is probable that it was the growing power of Syria had led to this affinity and alliance.]
