Matthew Henry on 1 Chronicles 16:37–end
The worship of God is not only to be the work of a solemn day now and then, brought in to grace a triumph; but it ought to be the work of every day. David therefore settles it here for a constancy, puts it into a method, which he obliged those that officiated to observe in their respective posts. In the tabernacle of Moses, and afterwards in the temple of Solomon, the ark and the altar were together; but, ever since Eli's time, they had been separated, and still continued so till the temple was built.

John Gill on 1 Chronicles 16:37
So he left there, before the ark of the covenant of the Lord, Asaph and his brethren,.... Whom he, that is, David, had appointed for the service of it:

Keil & Delitzsch on 1 Chronicles 16:37
And Zadok the priest, and his brethren the priests,.... These he left, having appointed them
to be before the tabernacle of the Lord, in the high place that was at Gibeon; namely, the tabernacle of Moses, which was removed from Nob thither in the days of Saul, and continued there to the times of Solomon, Ch1 21:28.
