William Burkitt on Revelation 17:12

Observe here, the angel farther explains to St. John this great mystery of the beast; declaring that the ten horns of the beast do signify ten kings, which should employ their power with the beast, and in conjunction with his established idolatry, to uphold his bloody religion; next their wicked unity is declared in giving their power and strength to the beast: They have one mind, verse 13 that is, they unanimously concur in aiding, strengthening, and assisting the beast, in using their power, and employing their authority, to maintain him in his idolatrous and Pagan-like superstitions.

Lastly it is declared for what end they thus concur together, in giving their power and strength to the beast, namely, to make war with the Lamb; that is, to take part with antichrist, and oppose Christ in his truth and gospel, in his ministers and members, in his children and servants, But the Lamb shall overcome them.

Some shall be converted by the power of the gospel, others shall be confounded, one way or other brought into subjection: for he is Lord of lords, and King of kings, that is, clothed with divine power.

Christ though a meek Lamb, yet is a mighty Lord. The titles here given him show his godhead and omnipotency: and having such a power, he knows how to fit instruments for his purpose; and those whom he will make use of in this work, shall be chosen persons, and faithful in the discharge of the trust committed to them. All that are faithful to Christ, shall share with him in his victory.
