2 Chronicles 20:19-21

MLV(i) 19 And the Levites, of the sons of the Kohathites and of the sons of the Korahites, stood up to praise Jehovah, the God of Israel, with an exceedingly 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 you* inhabitants of Jerusalem. Believe in Jehovah your* God, so you* will be established. Believe his prophets, so you* will prosper.
21 And when he had taken counsel with the people, he appointed those who should sing to Jehovah and give praise in holy array, as they went out before the army and say, Give thanks to Jehovah. For his loving kindness is everlasting.
