John Calvin Commentary Psalms 67:3

"Let the peoples praise thee, O God; Let all the peoples praise thee." — Psalms 67:3 (ASV)

Let the people praise you, O God! Having spoken of all nations participating in the saving knowledge of God, he next tells us that they would proclaim His goodness and exhorts them to the exercise of gratitude. The repetition itself clearly shows that he alludes to an event of a new and unprecedented kind.

Had the allusion been to some such manifestation of His favor as He ordinarily made to the Jews, we would not have looked for the same vehemence of expression. First he says, Let the people praise you; then he adds, Let all the people praise you. Afterward, he repeats the exclamation once more.

But he appropriately mentions, in between, rejoicing, and the reason for it, since it is impossible that we can praise God rightly unless our minds are tranquil and cheerful—unless, as persons reconciled to God, we are animated with the hope of salvation, and the peace of God, which passes all understanding, reigns in our hearts (Philippians 4:7).

The cause assigned for joy itself plainly points to the event of the calling of the Gentiles. The reference is not to that government of God which is general in its nature, but to that special and spiritual jurisdiction which He exercises over the Church, in which He cannot properly be said to govern any but those whom He has gathered under His sway by the doctrine of His law. The word righteousness is inserted in commendation of His government. Language almost identical is used by Isaiah and Micah when they speak of the times in which the word of salvation would be diffused throughout all the earth (Isaiah 11:4; Micah 4:3).
