Charles H. Spurgeon on Psalms 93:1

The LORD reigneth, i.e., the Lord has become King (Ps 96:10 97:1 99:1). The formula proclaimed at the accession of earthly sovereigns (2Sa 15:10 1Ki 1:11,13; margin, 2Ki 9:13, "Jehu reigneth"). The reference is not to the ordinary and constant government of God, but to his assuming a new and glorious kingdom. The arrogant proclamation of the world power was virtually "the Assyrian reigneth"; the overthrow of him was God's counter proclamation: "The Lord (Jehovah) reigneth." The antitypical sense is, the world powers under Antichrist, energized by Satan (Re 16:14 17:12-14,17), shall make one last desperate stroke, seemingly for the moment successful, for the dominion of the earth, in defiance of the Lord, (2Th 2:3-12) But Christ will take his great power and reign as King of kings and Lord of lords, having overthrown utterly the antichristian enemy. (Isa 24:23 Ob 1:21; Zec 14:9 Re 11:15,17 19:6.) A. R. Fausset.
