'Shackles' in the Bible

For his hands and feet had often been bound with chains and shackles, but he had torn the chains apart and broken the shackles in pieces. No one was strong enough to subdue him.

For Jesus had started commanding the evil spirit to come out of the man. (For it had seized him many times, so he would be bound with chains and shackles and kept under guard. But he would break the restraints and be driven by the demon into deserted places.)
