Matthew 12:27 (KJV)

Then was brought unto him one possessed with a devil, blind, and dumb: and he healed him, insomuch that the blind and dumb both spake and saw.

And all the people were amazed, and said, Is not this the son of David?

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

And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:

And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?

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

Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.

He that is not with me is against me; and he that gathereth not with me scattereth abroad.

Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.

And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
