2 Chronicles 20:15-30

And he said, “Listen, all Judah and inhabitants of Jerusalem and King Jehoshaphat, thus says Yahweh to you: ‘Do not be afraid and do not be dismayed before this great multitude, for the battle is not yours, but God’s. Tomorrow go down against them. Behold, they are coming up the ascent of Ziz. And you will find them at the end of the valley facing the desert of Jeruel. There will be no need for you to fight in this battle. Take your stand! Stand and see the deliverance of Yahweh among you, O Judah and Jerusalem! Do not fear and do not be dismayed. Tomorrow go out before them and Yahweh will be with you.’ ” Then Jehoshaphat bowed his face down to the ground, and all Judah and the inhabitants of Jerusalem fell before Yahweh to worship Yahweh. Then the Levites, from the Kohathites and from the Korahites stood up to praise Yahweh the God of Israel with an exceedingly loud voice. And they rose up early in the morning and went out to the desert of Tekoa. And when they went out, Jehoshaphat stood and said, “Hear me, O Judah and inhabitants of Jerusalem! Believe in Yahweh your God, and you shall be established! Believe in his prophets, and you shall succeed!” And when he had taken counsel with the people, he appointed singers to Yahweh who were giving praise to the splendor of his holiness when they went out before the army. And they said, “Give thanks to Yahweh, for his loyal love is everlasting!” And when they began with singing and praise, Yahweh set ambushes against the people of Ammon, Moab, and Mount Seir who were coming against Judah. And they were defeated when the people of Ammon and Moab rose up against the inhabitants of Mount Seir to destroy and demolish them. And when the inhabitants of Seir had made an end of them, each helped to destroy his comrade. And Judah came against the watchtower of the wilderness. And they looked at the crowd, and behold, corpses were lying on the ground. There was none who had escaped. When Jehoshaphat came with his people to plunder their booty, they found among them in abundance possessions, corpses, and precious items. And they took plunder for themselves until they could carry no more. And they were three days in plundering the booty, for it was abundant. And on the fourth day, they assembled in the Valley of Berakah, for there they blessed Yahweh. Therefore the name of that place is called the Valley of Berakah up to this day. And all the men of Judah and Jerusalem returned, and Jehoshaphat was at their head in returning to Jerusalem with joy, for Yahweh caused them to rejoice over their enemies. And they came to Jerusalem with harps, stringed instruments, and trumpets to the house of Yahweh. And the fear of God came upon all the kingdoms of the earth when they heard that Yahweh had fought against the enemies of Israel. So the kingdom of Jehoshaphat was at rest, since his God gave rest to him all around.
