1 Chronicles 16:4

“And he appointed certain of the Levites to minister before the ark of the Lord, etc.] 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.”

“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.”

“This passage is interposed by the writer of Chronicles between two sentences of the parallel passage in Samuel. It contains a detailed account of the service which David instituted at this time, a service out of which grew the more elaborate service of the temple. The language of much of the passage is remarkably archaic, and there can be no reasonable doubt that it is in the main an extract from a record of the time of David. 1 Chronicles 16:5 The occurrence of the name “Jeiel” twice in this list is considered suspicious. Hence, the first “Jeiel” is thought to be a corrupt reading for “Aziel” 1 Chronicles 15:20, or “Jaaziel” 1 Chronicles 15:18. 1 Chronicles 16:8 The Psalm here put before us…”

“To thank, and praise - All our rejoicings should express themselves in thanksgivings to him, from whom all our comforts are received. 1 Chronicles 16:7”

“he appointed: Ch1 15:16, Ch1 23:2-6, Ch1 24:3 minister: Ch1 16:37-42, Ch1 23:27-32; Num 18:1-6 to record: Ch1 16:8; Psa 37:1, Psa 70:1 \*titles Psa 103:2, Psa 105:5; Isa 62:6, Isa 62:7 the Lord God: Gen 17:7, Gen 32:28, Gen 33:20 \*marg. Kg1 8:15; Psa 72:18, Psa 106:48 1 Chronicles 16:5”

“When the solemnity of the transfer of the ark, the sacrificial meal, and the dismissal of the people with a blessing, and a distribution of food, were ended, David set in order the service of the Levites in the holy tent on Zion. He appointed before the ark, from among the Levites, servants to praise and celebrate God, i.e., singers and players to sing psalms as a part of the regular worship. להזכּיר, literally, "in order to bring into remembrance," is not to praise in general, but is to be interpreted according to the להזכּיר in the superscription of Ps 38 and Psa 70:1-5, by which these psalms are designated as the appointed prayers at the presentation of the Azcarah of the meat-offering (…”
