Exodus 28:12-14

Young's Literal Translation

¹² `And thou hast set the two stones on the shoulders of the ephod -- stones of memorial to the sons of Israel -- and Aaron hath borne their names before Jehovah, on his two shoulders, for a memorial.

¹³ `And thou hast made embroidered things of gold,

¹⁴ and two chains of pure gold, wreathed work thou dost make them, work of thick bands, and thou hast put the thick chains on the embroidered things.
