Matthew 12:24-30

24 But when the Pharisees heard it they said, "It is only by Be-el'zebul, the prince of demons, that this man casts out demons."
25 Knowing their thoughts, he said to them, "Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand;
26 and if Satan casts out Satan, he is divided against himself; how then will his kingdom stand?
27 And if I cast out demons by Be-el'zebul, by whom do your sons cast them out? Therefore they shall be your judges.
28 But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you.
29 Or how can one enter a strong man's house and plunder his goods, unless he first binds the strong man? Then indeed he may plunder his house.
30 He who is not with me is against me, and he who does not gather with me scatters.
