16 David then told the chiefs of the Levites to appoint their brothers the singers to sing out joyfully, accompanied by musical instruments: stringed instruments, harps,+ and cymbals.+

17 So the Levites appointed Heʹman+ the son of Joel and, of his brothers, Aʹsaph+ the son of Ber·e·chiʹah and, of the Me·rarʹites their brothers, Eʹthan+ the son of Kush·aʹiah.

25 Further, David and the chiefs of the groups for the service separated some of the sons of Aʹsaph, Heʹman, and Je·duʹthun+ to serve by prophesying with the harps, the stringed instruments,+ and the cymbals.+ The list of the official men for this service was, 2 of the sons of Aʹsaph: Zacʹcur, Joseph, Neth·a·niʹah, and Ash·a·reʹlah, the sons of Aʹsaph under the direction of Aʹsaph, who prophesied under the direction of the king.
