37 So he left there, before the ark of the covenant of Yahweh, Asaph and his brothers, to minister before the ark continually, as every day’s work required; 38 and Obed-Edom with their brothers, sixty-eight; Obed-Edom also the son of Jeduthun and Hosah to be doorkeepers; 39 and Zadok the priest, and his brothers the priests, before the tabernacle of Yahweh in the high place that was at Gibeon, 40 to offer burnt offerings to Yahweh on the altar of burnt offering continually morning and evening, even according to all that is written in the law of Yahweh, which he commanded to Israel; 41 and with them Heman and Jeduthun, and the rest who were chosen, who were mentioned by name, to give thanks to Yahweh, because his loving kindness endures forever;

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.
