John Calvin Commentary Mark 1:26

"And the unclean spirit, tearing him and crying with a loud voice, came out of him." — Mark 1:26 (ASV)

When the unclean spirit had torn him: Luke uses a milder phrase, when the devil had thrown him down; but they agree perfectly regarding the meaning, for the purpose of both was to show that the devil left the man in a violent manner. He threw down the unhappy man as if he had intended to tear him, but Luke says that the attempt was unsuccessful; for he hurt him nothing. This does not mean that the attack was in no way accompanied by injury, or at least by some feeling of pain, but rather that the man was afterward delivered from the devil and restored to perfect health.
