the Levitical singers dressed in fine linen and carrying cymbals, harps, and lyres were standing east of the altar, and with them were 120 priests blowing trumpets. The Levitical singers were descendants of Asaph, Heman, and Jeduthun and their sons and relatives.

The singers, the descendants of Asaph, were at their stations according to the command of David, Asaph, Heman, and Jeduthun the king’s seer. Also, the gatekeepers were at each gate. None of them left their tasks because their Levite brothers had made preparations for them.
