This psalm seems to have been composed upon the occasion of carrying the ark from the house of Obed-edom into the city of Zion, 2 Sam. vi, 12, 17. But as Zion was a type of the church, and the ark a type of Christ, so it has a farther reference, even to Christ's ascension into heaven, and to the spreading of his kingdom in all parts of the world. It contains an exhortation to rejoice in God, ver. 1-4. A prophecy of Christ's ascension, and of the calling of the Gentiles, ver. 5-9. To the chief musician, A psalm for the sons of Korah.
