It was a glorious day when the ark of God was safely lodged in the tent David had pitched for it. That good man had his heart much upon it, could not sleep contentedly till it was done, Psa 132:4, Psa 132:5.
I. The circumstances of the ark were now, 1. Better than what they had been. It had been obscure in a country town, in the fields of the wood; now it was removed to a public place, to the royal city, where all might resort to it. It had been neglected, as a despised broken vessel; now it was attended with veneration, and God was enquired of by it. It had borrowed a room in a private house, which it enjoyed by courtesy; now it had a habitation of its own entirely to itself, was set in the midst of it, and not crowded into a corner. Note, Though God's word and ordinances may be clouded and eclipsed for a time, they shall at length shine out of obscurity. Yet, 2. They were much short of what was intended in the next reign, when the temple was to be built. This was but a tent, a poor mean dwelling; yet this was the tabernacle, the temple which David in his psalms often speaks of with so much affection. David, who pitched a tent for the ark and continued steadfast to it, did far better than Solomon, who built a temple for it and yet in his latter end turned his back upon it. The church's poorest times were its purest.
II. Now David was easy in his mind, the ark was fixed, and fixed near him. Now see how he takes care, 1. That God shall have the glory of it. Two ways he gives him honour upon this occasion: - (1.) By sacrifices (Ch1 16:1), burnt-offerings in adoration of his perfections, peace-offerings in acknowledgment of his favours. (2.) By songs: he appointed Levites to record this story in a song for the benefit of others, or to celebrate it themselves by thanking and praising the God of Israel, Ch1 16:4. All our rejoicings must express themselves in thanksgivings to him from whom all our comforts are received. 2. That the people shall have the joy of it. They shall fare the better for this day's solemnity; for he gives them all what is worth coming for, not only a royal treat in honour of the day (Ch1 16:3), in which David showed himself generous to his subjects, as he had found God gracious to him (those whose hearts are enlarged with holy joy should show it by being open-handed); but (which is far better) he gives them also a blessing in the name of the Lord, as a father, as a prophet, Ch1 16:2. He prayed to God for them, and commended them to his grace. In the name of the Word of the Lord (so the Targum), the essential eternal Word, who is Jehovah, and through whom all blessings come to us.

To every one a loaf of bread - A whole cake. A good piece of flesh; "the sixth part of an ox, and the sixth part of a hin of wine." - T. See Sa2 6:18-20; see Jarchi also.

Asaph the chief,.... Of those that were now appointed: otherwise, of the three principal singers, Heman was the chief, and Asaph next, Ch1 6:33.

and next to him Zechariah, Jeiel, Shemiramoth, and Jehiel, and Mattithiah, and Eliab, and Benaiah, and Obededom, and Jeiel, with psalteries, and with harps; to play upon them before the ark at the same time the psalms and songs were vocally sung; the above persons are such as are named before, Ch1 15:18,

but Asaph made a sound with cymbals; he struck and played upon them, see Ch1 15:19.

he appointed certain of the Levites to minister before the ark of the Lord--No sooner was the ark deposited in its tent than the Levites, who were to officiate in the choirs before it, entered upon their duties. A select number of the musicians were chosen for the service from the list (Ch1 15:19-21) of those who had taken a prominent part in the recent procession. The same arrangement was to be observed in their duties, now that the ark again was stationary; Asaph, with his associates, composing the first or principal company, played with cymbals; Zechariah and his colleagues, with whom were conjoined Jeiel and Obed-edom, forming the second company, used harps and similar instruments.
