'Fetters' in the Bible

thus said Yahweh to me--"Make for yourself fetters and yokes and put them on your neck,

Then he blinded the eyes of Zedekiah and tied him up with bronze fetters to bring him [to] Babylon.

Then he made blind the eyes of Zedekiah, and they tied him up with bronze fetters, and the king of Babylon brought him [to] Babylon. And he put him in {prison} until the day of his death.
