Exodus 28:27-29

New Revised Standard Version Catholic Edition

²⁷ 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 decorated band of the ephod. ²⁸ The breastpiece shall be bound by its rings to the rings of the ephod with a blue cord, so that it may lie on the decorated band of the ephod, and so 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 on his heart when he goes into the holy place, for a continual remembrance before the Lord.
