⁶ They were all with their fathers Asaf, Y’dutun and Heman to sing with cymbals, lutes and lyres in the house of Adonai, serving in the house of God under the direction of the king. ⁷ Their number, together with their kinsmen who had been instructed in singing to Adonai, was 288, all well trained. ⁸ Whether great or small, teacher or talmid, they cast lots for their term of duty.
