Luke 11:17-19 New Revised Standard Version, Anglicised (NRSVA)
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.
