25 Further, David and the chiefs+ of the service groups+ separated for the service some of the sons of Aʹsaph, Heʹman+ and Je·duʹthun+ the ones prophesying with the harps,+ with the stringed instruments+ and with the cymbals.+ And from their number the official men for their service came to be.

12 and the Levites+ that were singers belonging to all of them, namely, to Aʹsaph,+ to Heʹman,+ to Je·duʹthun+ and to their sons and to their brothers clothed in fine fabric with cymbals+ and with stringed instruments+ and harps,+ were standing to the east of the altar and along with them priests to [the number of] a hundred and twenty sounding the trumpets;+

30 Hez·e·kiʹah the king and the princes+ now said to the Levites to praise Jehovah in the words of David+ and of Aʹsaph+ the visionary. So they began to offer praise even with rejoicing,+ and they kept bending down and prostrating themselves.+
