Revelation 19:6

“And I heard, as it were, the voice of a great multitude, etc.] Even of all the servants of the Lord, and them that fear him, small and great; a vast multitude of converted Jews and Gentiles, in the several parts of the world, who in answer to the voice out of the throne, which came with great power and energy, lift up their voices in praise to God, both for their own conversion, and for the downfall of Babylon: and as the voice of many waters: falling down in a descent, or in rough and rocky places, which make a great noise, and is heard afar off; and such must be the united voice of so great a multitude of converts as will be gathered together everywhere at this time: the same metaphor is…”

“many waters--Contrast the "many waters" on which the whore sitteth (Rev 17:1). This verse is the hearty response to the stirring call, "Alleluia! Praise our God" (Rev 19:4-5). the Lord God omnipotent--Greek, "the Omnipotent." reigneth--literally, "reigned": hence reigneth once for all. His reign is a fact already established. Babylon, the harlot, was one great hindrance to His reign being recognized. Her overthrow now clears the way for His advent to reign; therefore, not merely Rome, but the whole of Christendom in so far as it is carnal and compromised Christ for the world, is comprehended in the term "harlot."

In the former case it was distinct; here it was confused - bearing a resemblance to the sound of roaring waters, or to muttering thunder, but less distinct than the former. This phrase would imply: (a)A louder sound; and, (b)That the sound was more remote, and…”

“And I heard the voice of a great multitude. So all his servants did praise him. The Almighty reigneth - More eminently and gloriously than ever before. Revelation 19:7”

“19:6-8 The focus of the final thunderous Praise the Lord! is that God reigns as the Almighty in complete supremacy (see 1:8; 4:8; 11:17; 15:3; 16:7, 14; 19:15; 21:22).”

“and as the voice of many: Rev 1:15, Rev 14:2; Eze 1:24, Eze 43:2 and as the voice of mighty: Rev 4:5, Rev 6:1, Rev 8:5, Rev 14:2, Rev 19:6; Job 40:9; Psa 29:3-9, Psa 77:18 for: Rev 11:15-18, Rev 12:10, Rev 21:22; Psa 47:2, Psa 47:7, Psa 93:1, Psa 97:1, Psa 97:12, Psa 99:1; Isa 52:7; Mat 6:13 Revelation 19:7”
