Matthew 12:24-27
12:24 But when the Pharisees heard this they said, “He does not cast out demons except by the power of Beelzebul, the ruler of demons!”
12:25 Now when Jesus realized what they were thinking, he said to them, “Every kingdom divided against itself is destroyed, and no town or house divided against itself will stand.
12:26 So if Satan casts out Satan, he is divided against himself. How then will his kingdom stand?
12:27 And if I cast out demons by Beelzebul, by whom do your sons cast them out? For this reason they will be your judges.
