Exodus 28:9-21

9And you shall take two onyx stones and engrave on them the names of the sons of Israel, 10six of their names on the one stone and the names of the remaining six on the 1other stone, according to their birth. 112As a jeweler engraves a signet, you shall engrave the two stones according to the names of the sons of Israel; you shall 3set them in filigree settings of gold. 12And you shall put the two stones on the shoulder pieces of the ephod, as stones of memorial for the sons of Israel, and Aaron shall 4carry their names before the Lord on his two shoulders 5as a memorial. 13And 6you shall make filigree settings of gold, 14and two chains of pure gold; you shall make them of twisted cord work, and you shall put the corded chains on the filigree settings.

15“7You shall make a 8breastpiece of judgment, the work of a skilled embroiderer; like the work of the ephod you shall make it: of gold, of violet, purple, and scarlet material, and fine twisted linen you shall make it. 16It shall be square and folded double, a 9span 10in length and a 11span 12in width. 17And you shall 13mount on it four rows of stones; the first row shall be a row of ruby, topaz, and emerald; 18and the second row a turquoise, a sapphire, and a diamond; 19and the third row a jacinth, an agate, and an amethyst; 20and the fourth row a beryl, and an onyx, and a jasper; they shall be set in gold filigree. 21The stones shall be engraved according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a signet, each 14according to his name for the twelve tribes.
