John Gill Commentary Psalms 92:8

"But thou, O Jehovah, art on high for evermore." — Psalms 92:8 (ASV)

But you, Lord, are most high for evermore
God is "the most High"; that is one of his names; he is above all, is higher than the highest; and he dwells on high, and looks down upon the inhabitants of the earth, and sees what is doing among them; and to him they will be accountable another day for what they do.

When wicked men perish, being destroyed, he will continue for ever in all his greatness, glory, and majesty; for there seems to be an antithesis in this verse to the former, or between wicked men and the Lord; and besides he endures for ever to inflict punishment upon them; and therefore it is that they shall be destroyed for ever.
