John Gill 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 Gill on Psalms 96:11),

the world, and they that dwell therein ;
men, the inhabitants of the world; that is, let them rejoice because this glorious King has taken to himself his great power, and reigns, (Revelation 11:15–17) .
