1 Chronicles 16:39BSB·traditional attribution

And David left Zadok the priest and his fellow priests before the tabernacle of the LORD at the high place in Gibeon

Matthew Henry Presbyterian @wholebiblehenry

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.

And with them,.... That is, with Zadok, and the priests with him at Gibeon: he left Heman and Jeduthun: or Ethan, two principal singers: and the rest that were chosen, who were expressed by name; see Ch1 16:18. to give thanks to the Lord, because his mercy endureth for ever; to praise him for his benefits, flowing from his grace and mercy continually.

HIS PSALM OF THANKSGIVING. (1Ch. 16:7-43) Then on that day David delivered first this psalm--Among the other preparations for this solemn inauguration, the royal bard had composed a special hymn for the occasion. Doubtless it had been previously in the hands of Asaph and his assistants, but it was now publicly committed to them as they entered for the first time on the performance of their sacred duties.
