'Fetters' in the Bible

And now do not carry on as scoffers,Or your fetters will be made stronger;For I have heard from the Lord God of hostsOf decisive destruction on all the earth.

Thus said Jehovah, 'The labour of Egypt, And the merchandise of Cush, And of the Sebaim -- men of measure, Unto thee pass over, and thine they are, After thee they go, in fetters they pass over, And unto thee they bow themselves, Unto thee they pray: Only in thee is God, And there is none else, no other God.
