Charles Spurgeon Commentary Mark 5:7

"and crying out with a loud voice, he saith, What have I to do with thee, Jesus, thou Son of the Most High God? I adjure thee by God, torment me not." — Mark 5:7 (ASV)

And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not.

Who was speaking then? The man himself, or the devil within him? It is very hard to tell; the man and the devil were two personalities, but they were so effectively blended into one that it is scarcely possible to tell when it was the man speaking, and when it was the devil. So, when sin enters a man, it becomes so completely ingrained in his very nature that, sometimes, we feel it must be the evil spirit speaking in the man, and yet it is not easy to be quite sure that it is so, and we cannot free the man himself from the guilt of his words and actions.

And cried with a loud voice, and said, What have I to do with thee, Jesus, thou son of the Most High God? I adjure thee by God, that thou torment me not.

Using the lips of this poor man, Satan spoke in him and through him. He is afraid of Christ. This dog of hell knows his Master, and crouches at his feet. He beseeches the "Son of the Most High God" not to torment him before his time.
