Here we have the mystery of this vision explained. The apostle wonders at the sight of this woman: the angel undertakes to open this vision to him, it being the key of the former visions; and he tells the apostle what was meant by the beast on which the woman sat; but it is so explained as still to need further explanation. 1. This beast was, and is not, and yet is; that is, it was a seat of idolatry and persecution; and is not, that is, not in the ancient form, which was pagan; and yet it is, it is truly the seat of idolatry and tyranny, though of another sort and form. It ascends out of the bottomless pit (idolatry and cruelty are the issue and product of hell), and it shall return thither and go into perdition. 2. This beast has seven heads, which have a double signification. (1.) Seven mountains - the seven hills on which Rome stands; and (2.) Seven kings - seven sorts of government. Rome was governed by kings, consuls, tribunes, decemviri, dictators, emperors who were pagan, and emperors who were Christian. Five of these were extinct when this prophecy was written; one was then in being, that is, the pagan emperor; and the other, that is, the Christian emperor, was yet to come, Rev 17:10. This beast, the papacy, makes an eighth governor, and sets up idolatry again. 3. This beast had ten horns; which are said to be ten kings which have as yet received no kingdoms; as yet, that is, as some, shall not rise up till the Roman empire be broken in pieces; or, as others, shall not rise up till near the end of antichrist's reign, and so shall reign but as it were one hour with her, but shall for that time be very unanimous and very zealous in that interest, and entirely devoted to it, divesting themselves of their prerogatives and revenues (things so dear to princes), out of an unaccountable fondness for the papacy.

These have one mind, and shall give their power and strength unto the beast - Therefore the ten horns must constitute the principal strength of the Latin empire; that is to say, this empire is to be composed of the dominions of ten monarchs independent of each other in every other sense except in their implicit obedience to the Latin Church. The beast in this and the preceding verse is distinguished from its horns, as the Whole Latin empire is distinguished in history from its constituent powers. See on Rev 17:16 (note).

These have one mind,.... The princes of these kingdoms, and their subjects, become, in time, of one religion; first they were Arians, and then Papists; and for a long series of time there was great unity between them, with respect to religious sentiments, being zealously attached to the church of Rome, its principles and practices:

and shall give their power and strength unto the beast; the Papal antichrist, the eighth king, and seventh head; to him they have given power to exercise all ecclesiastical authority in their kingdoms; as to ordain bishops, and deliver the pall to whom they will; to excommunicate offenders, and even lay their kingdoms under an interdict when they pleased; and have assisted and defended the popes of Rome with all their force, with all their might and main, and to the utmost of their power, and have engaged in what have been called the holy wars, at their motion; they have given their riches and wealth, which are called the forces of strength, Job 36:19 which they have, by various methods, drained them of; hence the whore of Rome came to be decked with gold, and pearls, and precious stones; yea, they have given them their kingdoms, and have received them from them, and become tributary to them.

one mind--one sentiment.

shall give--So Coptic. But A, B, and Syriac, "give."

strength--Greek, "authority." They become his dependent allies (Rev 17:14). Thus Antichrist sets up to be King of kings, but scarcely has he put forth his claim when the true KING OF KINGS appears and dashes him down in a moment to destruction.
