33 And these were the singers,+ the heads of the fathers of the Levites in the dining rooms,+ those set free from duty;+ for by day and by night it was their responsibility to be in the work.+

16 David now said to the chiefs of the Levites to station their brothers the singers+ with the instruments of song,+ stringed instruments+ and harps+ and cymbals,+ playing aloud to cause a sound of rejoicing to arise.
