The occasion of this psalm, seems to have been David's translation of the ark to Zion, which was managed with great solemnity and devotion. For the first words are the very same which Moses appointed for such occasions, Num. x, 35, and the following verses pursue the same matter. Thence he falls into a description of some of the glorious works of the God to whom this ark belonged. But because David knew that both himself and the ark were types of Christ, and that the church of Israel were a type of the catholick church, consisting of Jews and Gentiles, and that the legal administrations were types of those of the gospel, he therefore by the spirit of prophecy, looked through the types, to the great mysteries of Christ's resurrection and ascension, and of the special privileges of the Christian church, and of the conversion of the Gentiles, and intermixes passages, which immediately belong to these things, although the words be so ordered, that they carry a manifest allusion to the present actions, and may be applied to them, in a secondary sense. He first prays against God's enemies, and for his people, ver. 1-3. Then praises God, for his greatness and goodness, ver. 4-6. For his wonderful works, ver. 7-14. For his special presence in his church, ver. 15- 17. The ascension of Christ, and the salvation of his people, ver. 18-20. His victories over his enemies, and favours to his church, ver. 21-28. The accession of the Gentiles to the church, ver. 29- 31. An awful acknowledgment of the glory and grace of God, ver. 32-35. To the chief musician, A psalm or song of David.
