Matthew 12:27-29 New Revised Standard Version (NRSV)
27 If I cast out demons by Beelzebul, by whom do your own exorcists[a] cast them out? Therefore they will be your judges. 28 But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come to you. 29 Or how can one enter a strong man’s house and plunder his property, without first tying up the strong man? Then indeed the house can be plundered.
