Mark 5:6-13 (NKJV)
[6] When he saw Jesus from afar, he ran and worshiped Him.
[7] And he cried out with a loud voice and said, “What have I to do with You, Jesus, Son of the Most High God? I implore You by God that You do not torment me.”
[8] For He said to him, “Come out of the man, unclean spirit!”
[9] Then He asked him, “What is your name?”
And he answered, saying, “My name is Legion; for we are many.”
[10] Also he begged Him earnestly that He would not send them out of the country.
[11] Now a large herd of swine was feeding there near the mountains.
[12] So all the demons begged Him, saying, “Send us to the swine, that we may enter them.”
[13] And at once Jesus gave them permission. Then the unclean spirits went out and entered the swine (there were about two thousand); and the herd ran violently down the steep place into the sea, and drowned in the sea.
