Re 15:1-8. THE LAST SEVEN VIALS OF PLAGUES: SONG OF THE VICTORS OVER THE BEAST.
1. the seven last plagues--Greek, "seven plagues which are the last."
is filled up--literally, "was finished," or "consummated": the prophetical past for the future, the future being to God as though it were past, so sure of accomplishment is His word. This verse is the summary of the vision that follows: the angels do not actually receive the vials till Re 15:7; but here, in Re 15:1, by anticipation they are spoken of as having them. There are no more plagues after these until the Lord's coming in judgment. The destruction of Babylon (Re 18:2) is the last: then in Re 19:11-16 He appears.
