XVI David's sacrifices and alms, ver. 1-3. He appoints Levites to minister before the ark, ver. 4-6. His psalm of thanksgiving, ver. 7-36. Ministers and others are appointed to attend the ark continually, ver. 37-43.

Verse 4. To thank, and praise - All our rejoicings should express themselves in thanksgivings to him, from whom all our comforts are received.

Verse 7. First - Hereby it is implied, that after this he delivered many other psalms into their hands, to be sung by them to the praise of God in his public service. We shall find it in the same words, in Psalm cv, 1-15 and Psalm 9vi, 1-11, all but the three last verses.

Verse 35. From the Heathen - This psalm or prayer was made by David for the use of the church, not only in that present time, but in future ages, in which David foresaw by the spirit of prophecy, the Israelites would forsake God, and for their apostacy be dispersed among the Heathens. In the midst of our praises, we must not forget to pray for those servants of God that are in distress. When we are rejoicing in God's favours, we should remember our afflicted brethren, and pray for their deliverance as our own. We are members one of another.

Verse 37. He left - He appointed them their work and station there. Indeed no incense was burnt there, nor sacrifices offered, because the altars were not there. But David's prayers were directed as incense, and the lifting up of his hands as an evening sacrifice. So early did spiritual worship take place of ceremonial.

Verse 39. Zadok - The chief-priest at Gibeon, where the tabernacle and altar made by Moses still were, where also the ordinary sacrifices were offered, and the stated worship of God was performed, as the extraordinary worship was before the ark upon great occasions, as when God was consulted, which was to be done before the ark and by the high-priest, who was Abiathar.

Verse 40. Which he commanded Israel - These must be kept up; because however in their own nature they were inferior to prayer and praise, yet as they were types of the mediation of Christ, the observance of them was of mighty importance.
