David spoke to the chief of the Levites to appoint their brothers the singers, with instruments of music, psalteries and harps and cymbals, sounding aloud and lifting up the voice with joy.
So glorious psalm of thanksgiving and praise that David gave. The first that was sung in the establishing of the worship for the children of Israel as once again they built the tabernacle, brought the ark of the covenant, and began to establish the worship of God once more as the heart of the nation. And so David then appointed Asaph and his brethren to minister before the ark continually, as every day's work required.
