'Chains' in the Bible

This is the message that came to Jeremiah from the LORD after Nebuzaradan the captain of the guard had released him from Ramah, when he was bound in chains, along with all the exiles from Jerusalem and Judah who were being taken into exile in Babylon.

Now, look, I've freed you today from the chains that were on your hands. If you want to come with me to Babylon, come, and I'll look after you. But if you don't want to come with me to Babylon, don't. Look, the whole land lies before you, so go wherever it seems good and right for you to go."
