'Chains' in the Bible

A craftsman pours out the idol, and a {goldsmith} overlays it with gold, and [he] smelts chains of silver.

Thus says Yahweh: "The acquisition of Egypt and the merchandise of Cush and the Sabeans, tall men, shall pass over to you; they shall be yours, and they shall walk behind you. They shall pass over in chains, and they shall bow down to you; they will pray to you: 'Surely God [is] with you, and there is no [other]. Besides [him] [there is] no God.'"
