Luke 11:14 And He was casting out a demon, and it was mute; when the demon had gone out, the mute man spoke; and the crowds were amazed.

Luke 9:1 And He called the twelve together, and gave them power and authority over all the demons and toheal diseases.

Mark 5:9-13 “My name is Legion; for we are many.” And he began to implore Him earnestly not to send them out of the country. Now there was a large herd of swine feeding [b]nearby on the mountain. The demons implored Him, saying, “Send us into the swine so that we may enter them.” Jesus gave them permission. And coming out, the unclean spirits entered the swine; and the herd rushed down the steep bank into the sea, about two thousand of them; and they were drowned in the sea.
