Luke 11:14-23 New Revised Standard Version (NRSV)
Jesus and Beelzebul
14 Now he was casting out a demon that was mute; when the demon had gone out, the one who had been mute spoke, and the crowds were amazed. 15 But some of them said, “He casts out demons by Beelzebul, the ruler of the demons.” 16 Others, to test him, kept demanding from him a sign from heaven. 17 But he knew what they were thinking and said to them, “Every kingdom divided against itself becomes a desert, and house falls on house. 18 If Satan also is divided against himself, how will his kingdom stand? —for you say that I cast out the demons by Beelzebul. 19 Now if I cast out the demons by Beelzebul, by whom do your exorcists[a] cast them out? Therefore they will be your judges. 20 But if it is by the finger of God that I cast out the demons, then the kingdom of God has come to you. 21 When a strong man, fully armed, guards his castle, his property is safe. 22 But when one stronger than he attacks him and overpowers him, he takes away his armor in which he trusted and divides his plunder. 23 Whoever is not with me is against me, and whoever does not gather with me scatters.
