Matthew 12:24-28

But the Pharisees heard it and said, “This man casts out demons only by [the help of] Beelzebul (Satan) the prince of the demons.” Knowing their thoughts Jesus said to them, “Any kingdom that is divided against itself is being laid waste; and no city or house divided against itself will [continue to]stand. If Satan casts out Satan [that is, his demons], he has become divided against himself and disunited; how then will his kingdom stand? If I cast out the demons by [the help of]Beelzebul (Satan), by whom do your sons drive them out? For this reason they will be your judges. But if it is by the Spirit of God that I cast out the demons, then the kingdom of God has come upon you [before you expected it].
