Revelation 17:12

The ten horns, or ten kings, which thou sawest, as yet have received no kingdom, but shall receive power as kings one hour after the beast; or, as it is in the Greek, with the beast. According to the common interpretation, this must be referred to ten, or many kings, who are different from all the wicked kings that had been, and who should follow and live at the same time with the beast, by which here seems to be signified antichrist. Or, if by these ten kings we understand all the wicked kings, who were to come after St. John wrote, to the end of the world, they had not yet kingdoms, but the kingdoms which they should have, and all their vain happiness, would be very short, and at the same time they would be under the beast, and subject to him. (Witham) --- Ten horns. These denote ten kings or ten powers; namely, Goths, Huns, Alans, Vandals, Saxons, Burgundians, Franks, Heruli, Suevi, &c. the chief of the barbarians that invaded the Roman empire in the fifth century. --- They shall receive power as kings one hour after the beast; that is, they will serve under their own leaders, to assist pagan Rome a little against its enemies; and their one design is afterwards to take the fruitful provinces of Rome to themselves, which we know they did. (Pastorini) --- Ten kings. Ten lesser kingdoms, enemies also of the Church of Christ; which nevertheless shall be made instruments of the justice of God, for the punishment of Babylon. Some understand this of the Goths, Vandals, Huns, and other barbarous nations that destroyed the empire of Rome. (Challoner)
