The beast which thou sawest was, and is not,.... It is added at the end of the verse where the same description is given, "and yet is"; this beast is to be understood not of the devil, who "was" the god of this world, "is not", being cast out by Christ, and yet is in being; for he, the dragon, is distinguished from this beast, and indeed from him the beast has his seat, power, and authority, Revelation 13:1 nor any particular emperor, as Domitian, a cruel and savage one, who was in power in Vespasian's time, when he was abroad, and then was out of it upon his return, and yet afterwards was in again, being as one sent from hell, and went at last into perdition; but the Roman empire itself is intended, as we have seen, which carried and supported the Papacy; and variously may this be interpreted; as that it was in the hands of the Romans originally, and long continued with them, but now "is not", in John's time, being in the hands of Trajan, a Spaniard, "and yet is" in being, Rome being the metropolis of it: it was a very powerful and flourishing empire, "and is not", being destroyed by the Goths and Vandals, "and yet is" a large empire under the jurisdiction of antichrist; it was an idolatrous empire, which encouraged the worshipping of Heathen gods, "and is not" guilty of the same idolatrous practices it was, as the worshipping of Jupiter, Mars, c. "and yet is" much given to idolatry in another way, worshipping the virgin Mary, and other saints it "was" under kings, consuls, dictators, tribunes, decemvirs, and emperors, it "is not" in such a form of government, "and yet is" under its seventh head the pope; "Rome was", but "is not" the same it has been, in some respects, and yet is the same, for idolatry, cruelty, c. it has the image of old Rome, when Pagan, and under the power of the dragon and though antichrist was not risen up in the empire to an head, to supreme power yet it was in being in the apostles' times, and began to work, and by degrees to show itself. In short, the meaning is, that this beast "was" the Roman empire, as Pagan, described by a dragon with seven heads, and ten horns, with crowns on the heads, but is not as yet in the Apostle John's time, as Papal, described with seven heads, and ten horns, and crowns on the horns.

And shall ascend out of the bottomless pit: out of hell, from whence the antichristian beast has its power; see Revelation 11:8 otherwise all civil power is from God, but not antichristian power, that is from the devil:

and go into perdition; everlasting destruction, the lake which burns with fire and brimstone; this will be the end of the beast, Revelation 19:20.

and they that dwell on the earth shall wonder; the inhabitants of the Roman empire, earthly minded men, shall have the beast in great veneration, and follow and worship him; see Revelation 13:3

whose names were not written in the book of life from the foundation of the world; none but reprobates, not any of the elect of God, are the admirers and worshippers of antichrist; Revelation 13:3- :

when they beheld the beast that was, and is not, and yet is; the Roman empire in glory, under the emperors, destroyed by the Goths, and revived in the Papacy. The Vulgate Latin and Ethiopic versions leave out the last clause,

and yet is.

The beast that thou sawest was, and is not - In the close of the verse it is added, “and yet is” - “the beast that was, and is not, and yet is.” There are three things affirmed here: first, that there is a sense in which it might be said of the power here referred to, that it “was,” or that, before this, it had an existence; second, that there was a sense in which it might be said that it is “not,” that is, that it had become practically extinct; and third, that there is a sense in which that power would be so revived that it might be said that it “still is.” The “beast” here referred to is the same that is mentioned in Revelation 17:3, and in Revelation 13:1, Revelation 13:3,Revelation 13:11-16. That is, there was one great formidable power, having essentially the same origin, though manifested under somewhat different modifications, to one and all of which might, in their different manifestations, be given the same name, “the beast.”

And shall ascend out of the bottomless pit - ἐκ τῆς ἀβύσσου ek tēs abussou. On the meaning of the word here used, see the notes on Revelation 9:1. The meaning here is, that this power would seem to come up from the nether world. It would appear at one time to be extinct, but would revive again as if coming from the world over which Satan presides, and would, in its revived character, be such as might be expected from such an origin.

And go into perdition - That is, its end will be destruction. It will not be permanent, but will be overthrown and destroyed. The word perdition here is properly rendered by Prof. Stuart “destruction,” but nothing is indicated by the word of the “nature” of the destruction that would come upon it.

And they that dwell on the earth - The inhabitants of the earth generally; that is, the matter referred to will be so remarkable as to attract general attention.

Shall wonder - It will be so contrary to the regular course of events, so difficult of explanation, so remarkable in itself, as to excite attention and surprise.

Whose names were not written in the book of life from the foundation of the world - See this explained in the notes on Revelation 13:8. The idea seems to be, that those whose names are written in the book of life, or who are truly the friends of God, would not be drawn off in admiration of the beast, or in rendering homage to it.

When they behold the beast that was, and is not, and yet is - That is, the power that once was mighty; that had declined to such a state that it became, as it were, extinct; and that was revived again with so much of its original strength, that it might be said that it still exists. The fact of its being revived in this manner, as well as the nature of the power itself, seemed suited to excite this admiration.
