Matthew 12:24-27

24 But when the Pharisees heard it, they said, "It is only by Beelzebul, the ruler of the demons, that this fellow casts out the demons."
25 He knew what they were thinking and said to them, "Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand.
26 If Satan casts out Satan, he is divided against himself; how then will his kingdom stand?
27 If I cast out demons by Beelzebul, by whom do your own exorcists cast them out? Therefore they will be your judges.
