2-я Паралипоменон 19:8

Jehoshaphat's victory over the Moabites, Ammonites, and other nations; and the remaining items of information as to his reign. - Vv. 1-30. The victory over the hostile peoples who invaded Judah. In the succeeding time, the Moabites and Ammonites, in alliance with other tribes of Mount Seir, invaded Judah with the purpose of driving the people of God out of their country, and extirpating them (Ch2 20:1). On being informed of this invasion, Jehoshaphat sought help of the Lord, while he proclaimed a fast in the land, and in the temple before the assembled people prayed God for His help (Ch2 20:2-12); and received by the mouth of the prophet Jahaziel the promise that God would fight for Judah, and that king and people would next day behold the help the Lord would give (Ch2 20:13-18). And so it happened. On the following day, when the Judaean army, with the Levitic singers and players at their head, came into the wilderness Jeruel, their enemies had by the dispensation of God mutually destroyed each other (Ch2 20:19-24), so that Jehoshaphat and his people found the proposed battle-field full of corpses, and gathered spoil for three days, and then on the fourth day, in the Valley of Blessing, they praised the Lord for the wonderful deliverance; thereafter returning to Jerusalem with joy, again to thank the Lord in the house of God for His help (Ch2 20:25-30).

We have here a further account of the good reign of Jehoshaphat, I. His return in peace to Jerusalem (Ch2 19:1). II. The reproof given him for his league with Ahab, and his acting in conjunction with him (Ch2 19:2, Ch2 19:3). III. The great care he took thereupon to reform his kingdom (Ch2 19:4). IV. The instructions he gave to his judges, both those in the country towns that kept the inferior courts (Ch2 19:5-7), and those in Jerusalem that sat in the supreme judicature of the kingdom (Ch2 19:8-11).
