2 Chronicles 20
17 Ref You shall not need to fight in this [battle]: set yourselves, stand you still, and see the salvation of Yahweh with you, O Judah and Jerusalem; don't be afraid, nor be dismayed: tomorrow go out against them: for Yahweh is with you.
18 Ref Jehoshaphat bowed his head with his face to the ground; and all Judah and the inhabitants of Jerusalem fell down before Yahweh, worshipping Yahweh.
19 Ref The Levites, of the children of the Kohathites and of the children of the Korahites, stood up to praise Yahweh, the God of Israel, with an exceeding loud voice.
20 Ref They rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Jehoshaphat stood and said, Hear me, Judah, and you inhabitants of Jerusalem: believe in Yahweh your God, so shall you be established; believe his prophets, so shall you prosper.
21 Ref When he had taken counsel with the people, he appointed those who should sing to Yahweh, and give praise in holy array, as they went out before the army, and say, Give thanks to Yahweh; for his loving kindness endures forever.
22 Ref When they began to sing and to praise, Yahweh set liers-in-wait against the children of Ammon, Moab, and Mount Seir, who had come against Judah; and they were struck.
