2. Chronik 18:1

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.

Here is, I. Jehoshaphat growing greater. It was said before (Ch2 17:5) that he had riches and honour in abundance; and here it is said again that his wealth and honour increased upon him by piety and good management. II. Not growing wiser, else he would not have joined with Ahab, that degenerate Israelite, who had sold himself to work wickedness. What good could he get by a man that was so bad? What good could he do to a man that was so obstinately wicked - an idolater, a persecutor? With him he joined in affinity, that is, married his son Jehoram to Ahab's daughter Athaliah. 1. This was the worst match that ever was made by any of the house of David. I wonder what Jehoshaphat could promise himself by it. (1.) Perhaps pride made the match, as it does many a one, which speeds accordingly. His religion forbade him to marry his son to a daughter of any of the heathen princes that were about him - Thou shalt not take their daughters to thy sons; and, having riches and honour in abundance, he thought it a disparagement to marry him to a subject. A king's daughter it must be, and therefore Ahab's, little considering that Jezebel was her mother. (2.) Some think he did it in policy, hoping by this expedient to unite the kingdoms in his son, Ahab perhaps flattering him with hopes that he would make him his heir, when he intended no such thing. 2. This match drew Jehoshaphat, (1.) Into an intimate familiarity with Ahab. He paid him a visit at Samaria, and Ahab, proud of the honour which Jehoshaphat did him, gave him a very splendid entertainment, according to the splendour of those times: He killed sheep and oxen for him, plain meat, in abundance, Ch2 18:2. In this Jehoshaphat did not walk so closely as he should have done in the ways of his father David, who hated the congregati…

18:1-2 Jehoshaphat’s alliance with Ahab led him to compromise his faithfulness to the Lord (see 19:2-3; cp. 2 Cor 6:14-18). The marriage of his son Jehoram (2 Chr 21:1) to Ahab’s daughter Athaliah (22:2) brought Israel’s apostasy into Judah (see 21:5-6, 12-13; 22:1-4).
