Mark 3:24

And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.

And he called them unto him, and said unto them in parables, How can Satan cast out Satan?

And if a house be divided against itself, that house cannot stand.

And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.
