And the Levitical singers, all of them of Asaph, of Heman, of Jeduthun, with their sons and their brothers, being clothed in white linen, having cymbals and with harps and lyres, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets,

And of the sons of Heman: Jehiel and Shimei. And of the sons of Jeduthun: Shemaiah and Uzziel.

And the singers, the sons of Asaph were in their place, according to the command of David, and Asaph, and Heman, and Jeduthun, the king's seer. And the gatekeepers were at every gate. It was not for them to depart from their service; for their brothers the Levites prepared for them.
