Revelation 13:3

"And I saw one of his heads as it were wounded to death; and his deadly wound was healed." This further serves to identify the beast with Rome; and also to locate in time some of these important events.

Chapter seventeen shows us that there were seven kings and that they were successive; for he says, "five are fallen, one is, and one is yet to come." If this is the Caesar dynasty, as it evidently is, then the head, or king, with the deadly wound was clearly Julius Caesar the founder of the empire. And the wound of that head, the killing of Julius Caesar, did not kill the beast at all; the deadly wound was healed. Though Julius Caesar was killed as a protest against autocracy, it did not destroy it in the least; the empire lived on, and Julius was followed by other Caesars more autocratic than he would have dared to be. The deadly wound was healed and the beast lived on to do the Devil's work.
