A Mark On Cain

Genesis 4:14-15 (ESV Strong's)

14 Behold, you have driven me today away from the ground, and from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, and whoever finds me will kill me.” 15 Then the Lord said to him, “Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold.” And the Lord put a mark on Cain, lest any who found him should attack him.

I can’t help but wonder if this is the mark of the end-time beast who will oppose God. Everyone on earth will marvel at the beast and say, “Who can oppose him?”
