2 Chronicles 20:19-21

MSTC(i) 19 And the Levites and the children of the Kohathites and of the Korahites stood up to praise the LORD God of Israel with a loud voice on high. 20 And so they arose early in the morning and gat them out unto the wilderness of Tekoa. And as they went out Jehoshaphat stood and said, "Hear me, Judah and the inhabiters of Jerusalem: Believe in the LORD your God, and so shall ye continue: and believe his prophets and so shall ye prosper." 21 And he gave the people counsel, and set the singers of the LORD and them that praised in holy apparel, to go out before the army and to say, "Praise the LORD for his mercy lasteth ever."
