1 And I saw another sign in heaven, great and marvellous, seven angels having the seven last plagues [the seven last plagues are synchronical only with the seventh vial]; for in them is filled up the wrath of God.

...the whole chapter is declarative of the end purposed to result from the outpouring of the vials. It is declarative of the victory of the saints over the constituted authorities of the nations; and the subjection of these to the King of Kings because of manifested national judgment. They err also in supposing, that "the seven last plagues" are identical with "the seven vials."

The seven vials contain "the seven last plagues;" but the plagues and the vials are not severally synchronical. On the contrary, the seven last plagues are synchronical only with the seventh vial; and so much of the sixth as obtains between the advent of Christ and the opening of the judgments of the seventh, is the epoch when One of the Four Living Ones gives the plagues to the angels.

The seven last plagues are identical with the Seven Thunders; and as they are comprehended in the seventh vial, the giving of the plagues is represented in the presentation of the "seven golden vials." These vials contain much more than the "seven last plagues."
