2. Chronik 18:5

The prophet Jehu's declaration as to Jehoshaphat's alliance with Ahab, and Jehoshaphat's further efforts to promote the fear of God and the administration of justice in Judah. - Ch2 19:1-3. Jehu's declaration. Jehoshaphat returned from the war in which Ahab had lost his life, בּשׁלום, i.e., safe, uninjured, to his house in Jerusalem; so that the promise of Micah in Ch2 18:16 was fulfilled also as regards him. But on his return, the seer Jehu, the son of Hanani, who had been thrown into the stocks by Asa (Ch2 16:7.), met him with the reproving word, "Should one help the wicked, and lovest thou the haters of Jahve!" (the inf. with ל, as in Ch1 5:1; Ch1 9:25, etc.). Of these sins Jehoshaphat had been guilty. "And therefore is anger from Jahve upon thee" (על קצף as in Ch1 27:24). Jehoshaphat had already had experience of this wrath, when in the battle of Ramoth the enemy pressed upon him (Ch2 18:31), and was at a later time to have still further experience of it, partly during his own life, when the enemy invaded his land (2 Chron 20), and when he attempted to re-establish the sea trade with Ophir (Ch2 20:35.), partly after his death in his family (2 Chron 21 and Ch2 22:1-12). "But," continues Jehu, to console him, "yet there are good things found in thee (cf. Ch2 12:12), for thou hast destroyed the Asheroth..." אשׁרות = אשׁרים, Ch2 17:6. On these last words, comp. Ch2 12:14 and Ch2 17:4.

The story of this chapter we had just as it is here related in the story of the reign of Ahab king of Israel, 1 Kings 22. There it looks more creditable to Ahab than any thing else recorded of him that he was in league with so good a man as Jehoshaphat; here it is a great blemish in the reign of Jehoshaphat that he thus connected himself with so bad a man as Ahab. Here is, I. The alliance he contracted himself with Ahab (Ch2 18:1). II. His consent to join with him in his expedition for the recovery of Remoth - Gilead out of the hands of the Syrians (Ch2 18:2, Ch2 18:3). III. Their consulting with the prophets, false and true, before they went (v. 4-27). IV. The success of their expedition. Jehoshaphat hardly escaped (Ch2 18:28-32) and Ahab received his death's wound (Ch2 18:33, Ch2 18:34).

18:5-7 The 400 prophets were Ahab’s “yes-men.” Jehoshaphat wanted instead to hear from a prophet of the Lord, but Ahab knew in advance that such a prophet would contradict his court prophets.
