Exodus 28:28-29

21st Century King James Version

²⁸ And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a lace of blue, that it may be above the embroidered girdle of the ephod, and that the breastplate be not loosed from the ephod.

²⁹ And Aaron shall bear the names of the children of Israel on the breastplate of judgment upon his heart when he goeth in unto the holy place, for a memorial before the Lord continually.
