2 Chronicles 20:18-22 New American Bible, Revised Edition (NABRE)

18. Then Jehoshaphat knelt down with his face to the ground, and all Judah and the inhabitants of Jerusalem fell down before the Lord in worship.

19. Levites from among the Kohathites and Korahites stood up to sing the praises of the Lord, the God of Israel, their voices ever louder.

20. Early in the morning they went out to the wilderness of Tekoa. As they were going out, Jehoshaphat halted and said: “Listen to me, Judah and inhabitants of Jerusalem! Let your faith in the Lord, your God, be firm, and you will be firm. Have faith in his prophets and you will succeed.”

21. After taking counsel with the people, he appointed some to sing to the Lord and some to praise the holy Splendor as it went forth at the head of the army. They sang: “Give thanks to the Lord, whose love endures forever.”

22. At the moment they began their jubilant praise, the Lord laid an ambush against the Ammonites, Moabites, and those of Mount Seir who were coming against Judah, so that they were defeated.
