Matthew 12:24-27

24But the Pharisees heard it and said, “This man casts out demons only by [the help of] Beelzebul (Satan) the prince of the demons.”

25Knowing 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.

26If Satan casts out Satan [that is, his demons], he has become divided against himself and disunited; how then will his kingdom stand?

27If 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.
