The following comparative charts demonstrate that the sounding of the trumpets and the pouring out of the vials depict one and the same judgment; the vial judgment being a reiteration and recapitulation of the earlier trumpet judgment. Thus, both the trumpet and bowl judgments represent the same seven plagues [7-fold judgment] to come upon Babylon, the city where the Lord was crucified [old covenant Jerusalem].
