2. Chronik 18:15

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).

18:15 Ahab understood that Micaiah had not spoken the word of the Lord, perhaps because Micaiah’s answer used the same words as that of his rivals, or Micaiah might have been speaking with a sarcastic tone (18:14).
