John Gill's Bible Commentary Ver. 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.
Matthew Henry Commentary
Verses 1-6 - Though God's word and ordinances may be clouded and eclipsed for time, they shall shine out of obscurity. This was but a tent, a humbl dwelling, yet this was the tabernacle which David, in his psalms, ofte speaks of with so much affection. David showed himself generous to his subjects, as he had found God gracious to him. Those whose hearts ar enlarged with holy joy, should show it by being open-handed.
