Exodus 28:11-14

11As a jeweler engraves signets, so shall you engrave the two stones with the names of the sons of Israel. You shall enclose them in settings of gold filigree. 12And you shall set the two stones on the shoulder pieces of the ephod, as stones of remembrance for the sons of Israel. And aAaron shall bear their names before the Lord on his two shoulders bfor remembrance. 13You shall make settings of gold filigree, 14and two chains of pure gold, twisted like cords; and you shall attach the corded chains to the settings.
