2 Chronicles 20:20-30 - God Delivers Judah And Jerusalem
20 And so they arose early in the morning and gat them out unto the wilderness of Tekoa. And as they went out Jehoshaphat stood and said, "Hear me, Judah and the inhabiters of Jerusalem: Believe in the LORD your God, and so shall ye continue: and believe his prophets and so shall ye prosper." 21 And he gave the people counsel, and set the singers of the LORD and them that praised in holy apparel, to go out before the army and to say, "Praise the LORD for his mercy lasteth ever."
22 And what time they began to laud and praise, then the LORD set layers await against the children of Ammon and Moab and mount Seir, 23 to destroy them utterly and to wipe them out. And when they had made an end of the inhabiters of Seir, then they helped to destroy each other.
24 And when Judah came to Mizphah in the wilderness, they looked unto the multitude. And behold, they were dead carcasses fallen to the earth, and none escaped. 25 And Jehoshaphat and his people went to rob away the spoil of them and found among them abundance of goods and raiment and of pleasant Jewels, and caught from them more than they could carry away: so that they were three days in gathering of the spoil, it was so much. 26 And the fourth day they assembled in the valley of blessing, for there they blessed the LORD. And therefore they called the name of the said place the valley of blessing unto this day.
27 And so all the men of Judah and Jerusalem returned and Jehoshaphat among the thickest of them, for to go again to Jerusalem with gladness: for the LORD had made them to rejoice of their enemies. 28 And they came to Jerusalem with psalteries and harps and trumpets, even unto the house of the LORD.
29 And the fear of God fell in the kingdoms of all lands, when they had heard that the LORD fought against the enemies of Israel. 30 And so the realm of Jehoshaphat was in tranquility: for his God had given him rest on every side.
