'Chains' in the Bible

The word which came to Jeremiah from the Lord after Nebuzaradan the captain of the bodyguard had released him from Ramah, when he had taken him bound in chains among all the captives of Jerusalem and Judah who were being taken as exiles to Babylon.

But now, listen carefully, [because of your innocence] I am freeing you today from the chains which are on your hands. If you would prefer to come with me to Babylon, come, and I will look after you [carefully]; but if you would prefer not to come with me to Babylon, then do not do so. Look, all the land is before you; go wherever it seems good and right (convenient) for you to go.”
