Rev. 13:3 shows a beast (Antichrist) wounded to death as it says, "And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast."

In talking about the beast (Antichrist) Rev. 13:10 says, "He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints."

So is this beast an Islamic Muslim who is killing with a sword and he is wounded to death by a sword according to Rev. 13:14, "And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live."  Rev. 13:12 also says that the first beast's deadly wound was healed.

So if he is wounded to death by a sword and did live.  Was he resurrected from the dead since all the world wondered after the beast?  Is it one of those lying wonders where a body double could be used as a substitution to die for the real beast who then claims to be alive.  Or could a lookalike android of the beast who imitates the beast's voice be used as a substitution to pretend to die with blood inside a pouch inside the android pouring out when it is wounded? Since an android doesn't have a heartbeat, it would be considered dead.

Then according to Rev. 19:21 the Lord Jesus Christ kills the remnant of the Antichrist's armies gathered agains him with a sword coming out of his mouth.
