Luke 11: 14 - 23
14 Now he was casting out a demon that was dumb; when the demon had gone out, the dumb man spoke, and the people marveled.
15 But some of them said, "He casts out demons by Be-el'zebul, the prince of demons";
16 while others, to test him, sought from him a sign from heaven.
17 But he, knowing their thoughts, said to them, "Every kingdom divided against itself is laid waste, and a divided household falls.
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.
21 When a strong man, fully armed, guards his own palace, his goods are in peace;
22 but when one stronger than he assails him and overcomes him, he takes away his armor in which he trusted, and divides his spoil.
23 He who is not with me is against me, and he who does not gather with me scatters.
