Revelation 17:14

Here we have some account of the downfall of Babylon, to be more fully described in the following chapter. I. Here is a war begun between the beast and his followers, and the Lamb and his followers. The beast and his army, to an eye of sense, appear much stronger than the Lamb and his army: one would think an army with a lamb at the head of them could not stand before the great red dragon. But, II. Here is a victory gained by the Lamb: The Lamb shall overcome. Christ must reign till all enemies be put under his feet; he will be sure to meet with many enemies, and much opposition, but he will also be sure to gain the victory. III. Here is the ground or reason of the victory assigned; and this is taken, 1. From the character of the Lamb: He is King of kings and Lord of lords. He has, both by nature and by office, supreme dominion and power over all things; all the powers of earth and hell are subject to his check and control. 2.

These shall . . . war with the Lamb--in league with the beast. This is a summary anticipation of Rev 19:19. This shall not be till after they have first executed judgment on the harlot (Rev 17:15-16). Lord of lords, &c.--anticipating Rev 19:16. are--not in the Greek. Therefore translate, "And they that are with Him, called chosen, and faithful (shall overcome them, namely, the beast and his allied kings)." These have been with Christ in heaven unseen, but now appear with Him.
