2 Chronicles 20:18-21

Jehoshaphat bowed facedown on the ground. All the people of Judah and Jerusalem bowed down before the LORD and worshiped him. Then some Levites from the Kohathite and Korahite people stood up and praised the LORD, the God of Israel, with very loud voices. Jehoshaphat’s army went out into the Desert of Tekoa early in the morning. As they were starting out, Jehoshaphat stood and said, “Listen to me, people of Judah and Jerusalem. Have faith in the LORD your God, and you will stand strong. Have faith in his prophets, and you will succeed.” Jehoshaphat listened to the people’s advice. Then he chose men to be singers to the LORD, to praise him because he is holy and wonderful. As they marched in front of the army, they said, “Thank the LORD, because his love continues forever.”
