So they brought the ark of God,.... What is contained in these three verses is the same with II Samuel 6:17, see the notes there. See Gill on II Samuel 6:17. See Gill on II Samuel 6:18. See Gill on II Samuel 6:19.

And he appointed certain of the Levites to minister before the ark of the Lord,.... By singing the praises of God:

and to record; or bring to remembrance; to commemorate in a song the great and good things God had done for Israel as a people:

and to thank and praise the Lord God of Israel; for all his benefits, and the blessings of his goodness bestowed on them.

Asaph the chief,.... Of those that were now appointed: otherwise, of the three principal singers, Heman was the chief, and Asaph next, I Chronicles 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, I Chronicles 15:18,

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

Benaiah also and Jahaziel the priests,.... These were appointed to blow

with trumpets continually before the ark of the covenant of the Lord; morning and evening.

Then on that day,.... The ark was brought to Zion, and the above persons appointed to minister before it:

David delivered first this psalm to thank the Lord into the hand of Asaph and his brethren to be sung by them now, and on every proper occasion; and this seems to be the first that was delivered to them; afterwards there were many more, as the titles of the psalms show; the following is composed of part of two others, as they now stand in the book of Psalms. From hence, to the end of I Chronicles 16:22 is the same with Psalm 105:1, with a little variation, see the notes there; and from thence to the end of I Chronicles 16:33 is Psalm 96:1 which see; and I Chronicles 16:34 is the same with Psalm 106:1, see the notes there. See Gill on Psalm 106:1, Psalm 107:1, Psalm 105:1, Psalm 105:2, Psalm 105:3, Psalm 105:4, Psalm 105:5, Psalm 105:6, Psalm 105:7, Psalm 105:8, Psalm 105:9, Psalm 105:10, Psalm 105:11,on Psalm 105:12, Psalm 105:13, Psalm 105:14,on Psalm 105:15

And say ye, save us, O God of our salvation,.... The author of temporal, spiritual, and eternal salvation; the words are a direction to the singers, and those that sung with them, to express the prayer and doxology in the next verse, which both are the same with Psalm 106:47. See Gill on Psalm 106:47, Psalm 106:48; which David directed by a spirit of prophecy, foreseeing the people of Israel would be in captivity among the Heathens; though some think these were added by Ezra; for though there was in his time a return from the captivity, yet many still remained in it.

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:

to minister before the ark continually; in singing the praises of God:

as every day's work required; at the time of the morning and evening sacrifice, as Jarchi and Kimchi interpret it.

The Levites, the brethren of Asaph and Obededom, these were left before the ark to minister there:

Obededom also the son of Jeduthun; or Ethan, which some take to be another Obededom; but the "vau" may be explanative, "even Obededom":

and Hosah to be porters; these he left to be doorkeepers of the ark.

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, I Chronicles 21:28.

To offer burnt offerings unto the Lord,.... Which was the work of the priests only to do:

upon the altar of burnt offering continually morning and evening; the lambs of the daily sacrifice, which were a burnt offering, and only to be offered on the brasen altar at the tabernacle:

and to do according to all that is written in the law of the Lord, which he commanded Israel; with regard to them, and all other sacrifices, see Exodus 29:38.

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 I Chronicles 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.

And with them Heman and Jeduthun, with trumpets and cymbals,.... Or with them were the trumpets and cymbals, as Kimchi; or, as Piscator supplies it, with them he "left" the trumpets and cymbals:

for those that should make a sound; by striking upon them:

and with musical instruments of God; sacred ones, such as were devoted to his service, as psalteries and harps; the Syriac and Arabic versions carry the sense of the words quite differently, that these men did not sing with those musical instruments, but with a pleasant voice, and with pure and acceptable prayers, in humility and uprightness, glorified God:

and the sons of Jeduthun were porters; at the tabernacle in Gibeon.

And all the people departed, every man to his house,.... Having accompanied the ark to its place, and having praised the Lord for it, and been refreshed with food, see II Samuel 6:19.

and David returned to bless his house; his family; the Targum is,"to bless the people;''see II Samuel 6:20.
