Mark 5:2-5

When He got out of the boat, immediately a man from the tombs with an unclean spirit met Him, and he had his dwelling among the tombs. And no one was able to bind him anymore, even with a chain; because he had often been bound with shackles and chains, and the chains had been torn apart by him and the shackles broken in pieces, and no one was strong enough to subdue him. Constantly, night and day, he was screaming among the tombs and in the mountains, and gashing himself with stones.
