Mark 5:3-5

3This man lived in the burial caves and could no longer be restrained, even with a chain.

4Whenever he was put into chains and shackles—as he often was—he snapped the chains from his wrists and smashed the shackles. No one was strong enough to subdue him.

5Day and night he wandered among the burial caves and in the hills, howling and cutting himself with sharp stones.
