Luke 11:14-20

And [at another time] Jesus was casting out a demon, and it was [controlling a man so as to make him] mute; when the demon had gone out, the mute man spoke. And the crowds were awed. [Matt 12:22-24] But some of them said, “He drives out demons by [the power of] Beelzebul (Satan), the ruler of the demons.” Others, trying to test Him, were demanding of Him a sign from heaven. But He, well aware of their thoughts and purpose, said to them, “Every kingdom divided against itself is doomed to destruction; and a house divided against itself falls. If Satan also is divided against himself, how will his kingdom stand and continue to survive? For you are saying that I drive out demons by [the power of] Beelzebul. Now if I drive out the demons by Beelzebul, by whom do your sons [the Jewish exorcists] drive them out? For this reason they will be your judges. But if I drive out the demons by the finger of God, then the kingdom of God has already come upon you.
