In the below scripture it gives an account of Jesus driving out a demon
Mark 1:24-26........"What do you want with us, Jesus of Nazareth? Have you come to destroy us? I know who you are--the Holy One of God!" "Be quiet!" said Jesus sternly. "Come out of him!" The evil spirit shook the man violently and came out of him with a shriek.
Veronica of Indianapolis had demons of anger and murder in her, and when the demons saw what Bob Larson was going to do, they yelled, "Get away from me!!" Strong men had to restrain her -- she had ancestral curses of anger, bitterness and murder. Many people today without knowing it have demons in and around them, this leads to heavy drinking, anger, drugs etc
