Luke 11:16-18 King James Version (KJV)
16 And others, tempting him, sought of him a sign from heaven.
17 But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth.
18 If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub.
