Luke 11:13-19
English Standard Version
14Now he was casting out a demon that was mute. When the demon had gone out, the mute man spoke, and the people marveled.
15But some of them said, "He casts out demons by Beelzebul, the prince of demons,"
16while others, to test him, kept seeking from him a sign from heaven.
17But he, knowing their thoughts, said to them, "Every kingdom divided against itself is laid waste, and a divided household falls.
18And if Satan also is divided against himself, how will his kingdom stand? For you say that I cast out demons by Beelzebul.
19And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges.
