Matthew 12:24-28

But when the Pharisees heard it, they said, This man doth not cast out demons, but by Beelzebub the prince of the demons. And knowing their thoughts he 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 casteth out Satan, he is divided against himself; how then shall his kingdom stand? 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.
