Revelation 19:6

This praise followed and probably included that of the angels. Together all God’s servants in heaven now praised Him for the fact that He reigns, after destroying Babylon. In this proleptic statement they look forward to what is about to happen, namely, Jesus Christ’s return to earth and the beginning of His eternal reign. [Note: Beckwith, p. 726; Robertson, 6:449; Ladd, p. 246.] Here He receives the title "the Lord our God, the Almighty." This praise is appropriately great since Messiah’s earthly reign is the climax of history. Thus John heard a voice that sounded like multitudes of people, the roar of a huge waterfall, and loud claps of thunder announcing its arrival (cf. Ezekiel 1:24; Ezekiel 43:2; Daniel 10:6). The singers are evidently angels (cf. Revelation 6:1; Revelation 10:1-4; Revelation 11:15-17; Revelation 14:2).
