{18} And there are seven kings: {19} five are fallen, {20} and one is, {21} and the other is not yet come; and when he cometh, he must continue a short space.

(18) The beginning of these kings or emperors is almost the same as the beginning of the Church of Christ, which I showed before in see Geneva (2) Re 11:1. Namely from the 25th year after the passion of Christ, at which time the temple and church of the Jews was overthrown. In this year it came to pass by the providence of God, that that saying The beast was, and is not was fulfilled before the destruction of the Jews immediately following, came to pass. That was 809 years from the building of the city of Rome at which time John counted the emperors who had been, when he wrote these things, and foretells two others next to come: and with this purpose, that when this particular prediction of things to come should take effect, the truth of all other predictions in the Church, might be the more confirmed. God in ancient times mentioned this sign in the Law and Jeremiah confirmed it in De 18:1-22, Jer 28:8.

(19) Whose names are these: the first, Servius Sulpitius Galba, who was the seventh emperor of the people of Rome, the second Marcus Salvius Otho, the third Avlus Vitellius, the fourth, Titus Flavius Vespasianus, the fifth, Titus Vespasianus his son, of his own name.

(20) Flavius Domitian, son of the first Vespasian. For in the latter end of his days John wrote these things, as witnesses Irenaus; Lib. 5 adversus hareses.

(21) Nerua, The empire being now translated from the family of Flavius. This man reigned only one year, four months and nine days, as the history writers tell.

People's New Testament

17:10 And there are seven kings. We have found that a mountain is a symbol of an exalted man, or power. In the notes for Re 13:1-8 I have explained the kingdoms or powers, symbolized by these heads.

Wesley's Notes

17:10 And they are seven kings - Anciently there were royal palaces on all the seven Roman bills. These were the Palatine, Capitoline, Coelian, Exquiline, Viminal, Quirinal, Aventine hills. But the prophecy respects the seven hills at the time of the beast, when the Palatine was deserted and the Vatican in use. Not that the seven heads mean hills distinct from kings; but they have a compound meaning, implying both together. Perhaps the first head of the beast is the Coelian hill, and on it the Lateran, with Gregory VII. and his successors; the second, the Vatican with the church of St. Peter, chosen by Boniface VIII. the third, the Quirinal, with the church of St. Mark, and the Quirinal palace built by Paul II. and the fourth, the Exquiline hill, with the temple of St. Maria Maggiore, where Paul V. reigned. The fifth will be added hereafter. Accordingly, in the papal register, four periods are observable since Gregory VII. In the first almost all the bulls made in the city are dated in the Lateran; in the second, at St. Peter's; in the third, at St. Mark's, or in the Quirinal; in the fourth, at St. Maria Maggiore. But no fifth, sixth, or seventh hill has yet been the residence of any Pope. Not that the hill was deserted, when another was made the papal residence; but a new one was added to the other sacred palaces. Perhaps the times hitherto mentioned might be fixed thus: 1058 Wings are given to the woman. 1077 The beast ascends out of the sea. 1143 The forty - two months begin. 1810 The forty - two months end. 1832 The beast ascends out of the bottomless pit. 1836 The beast finally overthrown.

Jamieson-Fausset-Brown Bible Commentary

10. there are-Translate, "they (the seven heads) are seven kings."

five . one-Greek, "the five . the one"; the first five of the seven are fallen (a word applicable not to forms of government passing away, but to the fall of once powerful empires: Egypt, Eze 29:1-30:26; Assyria and Nineveh, Na 3:1-19; Babylon, Re 18:2; Jer 50:1-51:64; Medo-Persia, Da 8:3-7, 20-22; 10:13; 11:2; Greece, Da 11:4). Rome was "the one" existing in John's days. "Kings" is the Scripture phrase for kingdoms, because these kingdoms are generally represented in character by some one prominent head, as Babylon by Nebuchadnezzar, Medo-Persia by Cyrus, Greece by Alexander, &c.

the other is not yet come-not as Alford, inaccurately representing Auberlen, the Christian empire beginning with Constantine; but, the Germanic-Slavonic empire beginning and continuing in its beast-like, that is, HEATHEN Antichristian character for only "a short space." The time when it is said of it, "it is not" (Re 17:11), is the time during which it is "wounded to death," and has the "deadly wound" (Re 13:3). The external Christianization of the migrating hordes from the North which descended on Rome, is the wound to the beast answering to the earth swallowing up the flood (heathen tribes) sent by the dragon, Satan, to drown the woman, the Church. The emphasis palpably is on "a short space," which therefore comes first in the Greek, not on "he must continue," as if his continuance for some [considerable] time were implied, as Alford wrongly thinks. The time of external Christianization (while the beast's wound continues) has lasted for centuries, ever since Constantine. Rome and the Greek Church have partially healed the wound by image worship.

Matthew Henry's Concise Commentary

17:7-14 The beast on which the woman sat was, and is not, and yet is. It was a seat of idolatry and persecution, and is not; not in the ancient form, which was pagan: yet it is; it is truly the seat of idolatry and tyranny, though of another sort and form. It would deceive into stupid and blind submission all the inhabitants of the earth within its influence, except the remnant of the elect. This beast was seven heads, seven mountains, the seven hills on which Rome stands; and seven kings, seven sorts of government. Five were gone by when this prophecy was written; one was then in being; the other was yet to come. This beast, directed by the papacy, makes an eighth governor, and sets up idolatry again. It had ten horns, which are said to be ten kings who had as yet no kingdoms; they should not rise up till the Roman empire was broken; but should for a time be very zealous in her interest. Christ must reign till all enemies be put under his feet. The reason of the victory is, that he is the King of kings, and Lord of lords. He has supreme dominion and power over all things; all the powers of earth and hell are subject to his control. His followers are called to this warfare, are fitted for it, and will be faithful in it.

Matthew Henry's Whole Bible Commentary

Verses 7-13

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, v. 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.
