Albert Barnes Commentary Psalms 67:5

"Let the peoples praise thee, O God; Let all the peoples praise thee." — Psalms 67:5 (ASV)

Let the people praise thee ... - See (Psalms 67:5). The repetition shows that this was the principal thought in the mind of the author of the psalm. It expresses an earnest - an intense - desire, that all nations should acknowledge God as the true God, and praise him for his mercies.
