'Chains' in the Bible

The Spirit of the Lord is on me, because I am marked out by him to give good news to the poor; he has sent me to make well those who are broken-hearted; to say that the prisoners will be let go, and the blind will see, and to make the wounded free from their chains,

For he gave an order to the evil spirit to come out of the man. For frequently it would take a grip of him: and he was kept under control, and prisoned with chains; but parting the chains in two, he would be sent by the driving of the evil spirit into waste places.
