37 So he left Asaph and his brothers there before the ark of the covenant of the Lord to minister before the ark regularly, as every day's work required; 38 and Obed-Edom with his sixty-eight brethren, including Obed-Edom the son of Jeduthun, and Hosah, to be gatekeepers; 39 and Zadok the priest and his brethren the priests, before the tabernacle of the Lord at the high place that was at Gibeon, 40 to offer burnt offerings to the Lord on the altar of burnt offering regularly morning and evening, and to do according to all that is written in the Law of the Lord which He commanded Israel; 41 and with them Heman and Jeduthun and the rest who were chosen, who were designated by name, to give thanks to the Lord, because His mercy endures forever; 42 and with them Heman and Jeduthun, to sound aloud with trumpets and cymbals and the musical instruments of God. Now the sons of Jeduthun were gatekeepers. 43 Then all the people departed, every man to his house; and David returned to bless his house.

Commentary on 1 Chronicles 16:37-43
(Read 1 Chronicles 16:37-43)
The worship of God ought to be the work of every day. David put it into order. At Jerusalem, where the ark was, Asaph and his brethren were to minister before the ark continually, with songs of praise. No sacrifices were offered there, nor incense burnt, because the altars were not there; but David's prayers were directed as incense, and the lifting up of his hands as the evening sacrifice. So early did spiritual worship take place of ceremonial. Yet the ceremonial worship, being of Divine institution, must by no means be omitted; therefore at Gibeon, at the altars, the priests attended; for their work was to sacrifice and burn incense; and that they did continually, morning and evening, according to the law of Moses. As the ceremonies were types of the mediation of Christ, the observance of them was of great consequence. The attendance of his appointed ministers is right in itself, and encourages the people.
