Mark 3:20-30 HCSB
Then He went home, and the crowd gathered again so that they were not even able to eat. When His family heard this, they set out to restrain Him, because they said, “He’s out of His mind.”
The scribes who had come down from Jerusalem said, “He has Beelzebul in Him! ” and, “He drives out demons by the ruler of the demons! ”
So He summoned them and spoke to them in parables: “How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. If a house is divided against itself, that house cannot stand. And if Satan rebels against himself and is divided, he cannot stand but is finished!
“On the other hand, no one can enter a strong man’s house and rob his possessions unless he first ties up the strong man. Then he will rob his house. I assure you: People will be forgiven for all sins and whatever blasphemies they may blaspheme. But whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin” — because they were saying, “He has an unclean spirit.”
