Albert Barnes 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 thee, O God - May you incline them to praise you: a prayer that all people might so understand the character and ways of God, and might have such a sense of his claims upon them, as to lead them to praise him.

Let all the people praise thee - The people of all lands. See the notes at (Psalms 22:27). Compare (Psalms 66:4).
