21 And he gave counsel to the people, and he ordained the singers of the Lord, that they should praise him in their companies, and that they should go before the host, and say with according voice, Acknowledge ye to the Lord, for he is good; for his mercy is without end. (And he consulted with the people, and he ordained the singers of the Lord, to praise him in their companies, and to go before the army, and to sing together with a loud voice, Praise ye the Lord, for he is good; for his love endureth forevermore.)
