2. Chronik 17:6

Jehoshaphat's marriage alliance with Ahab, and his campaign with Ahab against the Syrians at Ramoth in Gilead. - Ch2 18:1. Jehoshaphat came into connection by marriage with Ahab through his son Joram taking Athaliah, a daughter of Ahab, to wife (Ch2 21:6); an event which did not take place on the visit made by Jehoshaphat to Ahab in his palace at Samaria, and recorded in Ch2 18:2, but which had preceded that by about nine years. That visit falls in the beginning of the year in which Ahab was mortally wounded at Ramoth, and died, i.e., the seventeenth year of Jehoshaphat's reign. But at that time Ahaziah, the son of Joram and Athaliah, was already from eight to nine years old, since thirteen years later he became king at the age of twenty-two; Kg2 8:26, cf. with the chronol. table to 1 Kings 12. The marriage connection is mentioned in order to account for Jehoshaphat's visit to Samaria (Ch2 18:2), and his alliance with Ahab in the war against the Syrians; but it is also introduced by a reference to Jehoshaphat's riches and his royal splendour, repeated from Ch2 17:5. In the opinion of many commentators, this is stated to account for Ahab's willingness to connect his family by marriage with that of Jehoshaphat. This opinion might be tenable were it Ahab's entering upon a marriage connection with Jehoshaphat which is spoken of; but for Jehoshaphat, of whom it is related that he entered into a marriage connection with Ahab, his own great wealth could not be a motive for his action in that matter. If we consider, first, that this marriage connection was very hurtful to the kingdom of Judah and the royal house of David, since Athaliah not only introduced the Phoenician idolatry into the kingdom, but also at the death of Ahaziah extirpated all the royal seed of the house of Da…

Here begin the life and reign of Jehoshaphat, who was one of the first three among the royal worthies, one of the best that ever swayed the sceptre of Judah since David's head was laid. He was the good son of a good father, so that, as this time, grace ran in the blood, even in the blood-royal. Happy the son that had such a father, to lay a good foundation in him and for him. Happy the father that had such a son, to build so wall upon the foundation he had laid! Happy the kingdom that was blessed with two such kings, two such reigns, together! In this chapter we have, I. His accession to and establishment in the throne (Ch2 17:1, Ch2 17:2, Ch2 17:5). II. His persona piety (Ch2 17:3, Ch2 17:4, Ch2 17:6). III. The course he took to promote religion in his kingdom (Ch2 17:7-9). IV. The mighty sway he bore among the neighbours (Ch2 17:10, Ch2 17:11). V. The great strength of his kingdom, both in garrisons and standing forces (Ch2 17:12-19). Thus was his prosperity the reward of his piety and his piety the brightest grace and ornament of his prosperity.
