1 Kings 22:2

“And it came to pass in the third year, etc.] Of the peace, before it was expired: that Jehoshaphat the king of Judah came down to the king of Israel; to Ahab, from Jerusalem to Samaria, reckoned thirty two miles f456; either to make peace with him, and put an end to the wars which subsisted between Israel and Judah since the division of the kingdom, (<112244>1 Kings 22:44) or to contract an affinity with him, by marrying his son to a daughter of Ahab, (<120818>2 Kings 8:18,26) or rather after peace was made, and that strengthened by the marriage; and so he went merely to pay a visit, as he judged he might then with great safety; and he and all his retinue were entertained by Ahab in a very…”

“Jehoshaphat the king of Judah came down to the king of Israel--It was singular that a friendly league between the sovereigns of Israel and Judah should, for the first time, have been formed by princes of such opposite characters--the one pious, the other wicked. Neither this league nor the matrimonial alliance by which the union of the royal families was more closely cemented, met the Lord's approval (Ch2 19:2). It led, however, to a visit by Jehoshaphat, whose reception in Samaria was distinguished by the most lavish hospitality (Ch2 18:2). The opportunity of this visit was taken advantage of, to push an object on which Ahab's heart was much set.”

“This visit indicates an entire change in the relations which we have hitherto found subsisting between the kingdoms of Israel and Judah. The common danger to which the two kingdoms were exposed from the growing power of Syria had probably induced them to forget their differences. Jehoshaphat’s eldest son, Jehoram, was married to Athaliah, the daughter of Ahab: but apparently the bond between the two families had not hitherto led to any very close intimacy, much less to any joint military expeditions. Jehoshaphat seems to have taken no part in the former Syrian wars of Ahab, nor did he join in the great league against the Assyrians (1 Kings 22:1 note). His visit now was probably one of mere…”

“Came down, &c. - It is strange, that so good a man would be so closely connected with a king revolted from the worship of God! But he appears to have been of too easy a temper, which betrayed him to many inconveniencies. 3 Kings (1 Kings) 22:3”

“22:2-4 Jehoshaphat and Ahab were in-laws by the marriage of Ahab’s daughter Athaliah to Jehoshaphat’s son Jehoram (2 Kgs 8:25-26). However cordial Jehoshaphat may have intended his visit to be, he quickly became involved in Ahab’s plan to occupy Ramoth-gilead. The Assyrian menace prevented Ahab from taking control of this key area that dominated the eastern end of the Plain of Jezreel. Now it needed to be taken by force, and Jehoshaphat placed his troops and horses at Ahab’s disposal.”
