Luke 11:19-21 New Revised Standard Version Catholic Edition (NRSVCE)
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.
