'Chains' in the Bible

Moreover he put out Zedekiah's eyes, and bound him with chains, to carry him to Babylon.

The word that came to Jeremiah from the LORD, after that Nebuzaradan the captain of the guard had let him go from Ramah, when he had taken him being bound in chains among all that were carried away captive of Jerusalem and Judah, which were carried away captive unto Babylon.

And now, behold, I loose thee this day from the chains which were upon thine hand. If it seem good unto thee to come with me into Babylon, come; and I will look well unto thee: but if it seem ill unto thee to come with me into Babylon, forbear: behold, all the land is before thee: whither it seemeth good and convenient for thee to go, thither go.

Then he put out the eyes of Zedekiah; and the king of Babylon bound him in chains, and carried him to Babylon, and put him in prison till the day of his death.
