Verses 1-6 Though God's word and ordinances may be clouded and eclipsed for a time, they shall shine out of obscurity. This was but a tent, a humble dwelling, yet this was the tabernacle which David, in his psalms, often speaks of with so much affection. 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.
Verses 7-36 Let God be glorified in our praises. Let others be edified and taught, that strangers to him may be led to adore him. Let us ourselves triumph and trust in God. Those that give glory to God's name are allowed to glory in it. Let the everlasting covenant be the great matter of our joy his people of old, be remembered by us with thankfulness to him. Show forth from day to day his salvation, his promised salvation by Christ. We have reason to celebrate that from day to day; for we daily receive the benefit, and it is a subject that can never be exhausted. In the midst of praises, we must not forget to pray for the servants of God in distress.
Verses 37-43 The worship of God ought to be the work of every day. David put it into order. At Jerusalem, where the ark was, Asaph and his brethren were to minister before the ark continually, with songs of praise. No sacrifices were offered there, nor incense burnt, because the altars were not there; but David's prayers were directed as incense, and the lifting up of his hands as the evening sacrifice. So early did spiritual worship take place of ceremonial. Yet the ceremonial worship, being of Divine institution, must by no means be omitted; therefore at Gibeon, at the altars, the priests attended; for their work was to sacrifice and burn incense; and that they did continually, morning and evening, according to the law of Moses. As the ceremonies were types of the mediation of Christ, the observance of them was of great consequence. The attendance of his appointed ministers is right in itself, and encourages the people.
