Luke 11:18-20

Revised Standard Version Catholic Edition

¹⁸ And if Satan also is divided against himself, how will his kingdom stand? For you say that I cast out demons by Be-el′zebul. ¹⁹ And if I cast out demons by Be-el′zebul, by whom do your sons cast them out? Therefore they shall be your judges. ²⁰ But if it is by the finger of God that I cast out demons, then the kingdom of God has come upon you.
