Exodus 28:27-29

Revised Standard Version

²⁷ And you shall make two rings of gold, and attach 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. ²⁸ And they shall bind the breastpiece by its rings to the rings of the ephod with a lace of blue, that it may lie upon the skilfully woven band of the ephod, and that the breastpiece shall not come loose from the ephod. ²⁹ So Aaron shall bear the names of the sons of Israel in the breastpiece of judgment upon his heart, when he goes into the holy place, to bring them to continual remembrance before the Lord.
