Albert Barnes Commentary Psalms 98:7

"Let the sea roar, and the fulness thereof; The world, and they that dwell therein;" — Psalms 98:7 (ASV)

Let the sea roar, and the fulness thereof - See the notes at Psalms 96:11.

The world, and they that dwell therein - The habitable world—the land—in contradistinction from the sea. Let there be universal praise on the water and the land.
