The central core of the psalm may either be taken as summons to the nations or as expression of desire for them. The depth of the longing or the stringency of the summons is wonderfully given by that fourfold repetition of the same words in vv. 3 and 5, with the emphatic "all of them" in the second clause of each. Not less significant is the use of three names for the aggregations of men--nations (ver. 2), peoples, and tribes. All are included, whatever bond knits them in communities, whatever their societies call themselves, however many they are. The very vagueness gives sublimity and universality. We can fill the vast outline drawn by these sweeping strokes; and wider knowledge should not be attended with narrowed desires, nor feebler confidence that the Light shall lighten every land. It is noticeable that in this central portion the deeds of God among the nations are set forth as the ground of their praise and joy in Him. Israel had the light of His face, and that would draw men to Him. But all peoples have the strength of His arm to be their defender, and the guidance of His hand by providences and in other ways unrecognised by them. The "judgments" here contemplated are, of course, not retribution for evil, but the aggregate of dealings by which God shows His sovereignty in all the earth. The psalmist does not believe that God's goodness has been confined to Israel, nor that the rest of the world has been left orphaned. He agrees with Paul, "That which may be known of God is manifest in them, for God manifested it to them."
