21 And 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 And when they began to sing and to praise, Yahweh set ambushers against the sons of Ammon, Moab, and mount Seir, that had come against Judah; and they were struck.
