also the Levites who were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brothers, arrayed in fine linen, with cymbals and stringed instruments and harps, stood at the east end of the altar, and with them one hundred twenty priests sounding with trumpets;)

and of the sons of Heman, Jehuel and Shimei; and of the sons of Jeduthun, Shemaiah and Uzziel.

The singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the gatekeepers were at every gate: they did not need to depart from their service; for their brothers the Levites prepared for them.
