Verse 1
18:1 And {1} after these things I saw another {2} angel come down from heaven, having great power; and the earth was lightened with his glory.
(1) The second passage (as I said before) see Geneva "Revelation 17:1" of the history of Babylon, is of the woeful fall and ruin of that whore of Babylon. This historical prediction concerning her, is threefold. The first a plain and simple foretelling of her ruin, in three verses Revelation 18:2-3 . The second a figurative prediction by the circumstances, from there to Revelation 18:4-20 . The third, a confirmation of the same by sign or wonder, to the end of the chapter Revelation 18:21-24 .
(2) Either Christ the eternal word of God the Father (as often elsewhere) or a created angel, and one deputed to this service, but thoroughly provided with greatness of power, and with light of glory, as the ensign of power.
