and the Levites, the singers, to all of them, to Asaph, to Heman, to Jeduthun, and to their sons, and to their brethren, clothed in white linen, with cymbals, and with psalteries, and harps, are standing on the east of the altar, and with them priests, to a hundred and twenty, blowing with trumpets --

and of the sons of Heman: Jehiel and Shimei; and of the sons of Jeduthun: Shemaiah and Uzziel --

And the singers, sons of Asaph, are on their station, according to the command of David, and Asaph, and Heman, and Jeduthun seer of the king, and the gate keepers are at gate and gate; it is not for them to turn aside from off their service, for their brethren the Levites have prepared for them.
