2 Chronicles 20:18-19

And Jehoshaphat bowed his head with his face to the ground; and all Judah and the inhabitants of Jerusalem fell down before Jehovah, worshipping Jehovah. 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.
