Augustine's comments on this very brief Psalm are likewise brief. Here all the nations are called to praise the Lord. Augustine particularly observes, "Let those rather listen who have refused to be the children of this city, since they have cut themselves off from the communion of all nations" (Augustine Psalms, loc. 338829, par. 1). The Lord who restores all nations to himself also calls those who reject him to turn and acknowledge him in praise.
