Exodus 28:27-29

Young's Literal Translation

²⁷ and thou hast made two rings of gold, and hast put them on the two shoulders of the ephod, beneath, over-against its front, over-against its joining, above the girdle of the ephod,

²⁸ and they bind the breastplate by its rings unto the rings of the ephod with a ribbon of blue, to be above the girdle of the ephod, and the breastplate is not loosed from the ephod.

²⁹ `And Aaron hath borne the names of the sons of Israel in the breastplate of judgment, on his heart, in his going in unto the sanctuary, for a memorial before Jehovah continually.
