Luke 11:13-19

If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him? And he was casting out a devil, and it was dumb. And it came to pass, when the devil was gone out, the dumb spake; and the people wondered. But some of them said, He casteth out devils through Beelzebub the chief of the devils. And others, tempting him, sought of him a sign from heaven. But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against an house falleth. If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub. And if I by Beelzebub cast out devils, by whom do your sons cast them out? therefore shall they be your judges.
