Mark 3:23-27

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