Exodus 39:19-21

Revised Standard Version

¹⁹ Then they made two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod. ²⁰ And they made two rings of gold, and attached them in front to the lower part of the two shoulder-pieces of the ephod, at its joining above the skilfully woven band of the ephod. ²¹ And they bound the breastpiece by its rings to the rings of the ephod with a lace of blue, so that it should lie upon the skilfully woven band of the ephod, and that the breastpiece should not come loose from the ephod; as the Lord had commanded Moses.
