Exodus 39:19-21

Complete Jewish Bible

¹⁹ They also made two gold rings and put them on the two ends of the breastplate, at its edge, on the side facing in toward the vest. ²⁰ Also they made two gold rings and attached them low on the front part of the vest’s shoulder-pieces, near the join, above the vest’s decorated belt. ²¹ Then they bound the breastplate by its rings to the rings of the vest with a blue cord, so that it could be on the vest’s decorated belt, and so that the breastplate would not swing loose from the vest — as Adonai had ordered Moshe.
