'Cast Out Demons' in the Bible

Many will say to me in that day, Lord, Lord, did we not prophesy by thy name, and by thy name cast out demons, and by thy name do many mighty works?

Heal the sick, raise the dead, cleanse the lepers, cast out demons: freely ye received, freely give.

But when the Pharisees heard it, they said, This man doth not cast out demons, but by Beelzebub the prince of the demons.

And if I by Beelzebub cast out demons, by whom do your sons cast them out? therefore shall they be your judges.

But if I by the Spirit of God cast out demons, then is the kingdom of God come upon you.
