2 Chronicles 20:19-21

American Standard Version

¹⁹ And the Levites, of the children of the Kohathites and of the children of the Korahites, stood up to praise Jehovah, the God of Israel, with an exceeding loud voice.

²⁰ And 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, O Judah, and ye inhabitants of Jerusalem: believe in Jehovah your God, so shall ye be established; believe his prophets, so shall ye prosper. ²¹ And when he had taken counsel with the people, he appointed them that should sing unto Jehovah, and give praise ^[a]in holy array, as they went out before the army, and say, Give thanks unto Jehovah; for his lovingkindness endureth for ever.
