Albert Barnes Commentary Psalms 100:1

"Make a joyful noise unto Jehovah, all ye lands." — Psalms 100:1 (ASV)

Make a joyful noise unto the Lord - See the notes at (Psalms 95:1).

All you lands - Margin, as in Hebrew, all the earth. The margin expresses the sense. The idea in the psalm is that praise did not pertain to one nation only; that it was not appropriate for one people merely; that it should not be confined to the Hebrew people, but that there was a proper ground of praise for all; there was that in which all nations, of all languages and conditions, could unite. The ground of that was the fact that they had one Creator (Psalms 100:3). The psalm is based on the unity of the human race; on the fact that there is one God and Father of all, and one great family on earth.
