Charles H. Spurgeon on Psalms 66:1

Whole Psalm. This Psalm is said to be recited on Easter day, by the Greek church: it is described in the Greek Bible as A Psalm of the Resurrection, and may be understood to refer, in a prophetic sense, to the regeneration of the world, through the conversion of the Gentiles. Daniel Cresswell.

Make a joyful noise unto God, all ye lands: Hebrew, all the earth; shout aloud for joy, as the people did at the return of the ark, so that the earth rang again. God shall show himself to be the God not of Jews only, but of Gentiles also; these shall as well cry Christ, as those Jesus; these say, Father, as those Abba. And, as there was great joy in Samaria when the gospel was there received (Ac 8:8), so shall there be the like in all other parts of the earth. John Trapp.
