Mark 3:24-30

And if a kingdom be divided against itself, that kingdom cannot stand. And if a house be divided against itself, that house will not be able to stand. And if Satan hath risen up against himself, and is divided, he cannot stand, but hath an end. But no one can enter into the house of the strong man, and spoil his goods, except he first bind the strong man; and then he will spoil his house. Verily I say unto you, All their sins shall be forgiven unto the sons of men, and their blasphemies wherewith soever they shall blaspheme: but whosoever shall blaspheme against the Holy Spirit hath never forgiveness, but is guilty of an eternal sin: because they said, He hath an unclean spirit.
