Exodus 28:9-21
“ Then you shall take two onyx stones and engrave on them the names of the sons of Israel:six of their names on one stone and six names on the other stone, in order of their birth.With the work of an engraver in stone, like the engravings of a signet, you shall engrave the two stones with the names of the sons of Israel. You shall set them in settings of gold.And you shall put the two stones on the shoulders of the ephod as memorial stones for the sons of Israel. So Aaron shall bear their names before the Lord on his two shoulders as a memorial.You shall also make settings of gold,and you shall make two chains of pure gold like braided cords, and fasten the braided chains to the settings.“ You shall make the breastplate of judgment. Artistically woven according to the workmanship of the ephod you shall make it: of gold, blue, purple, and scarlet thread, and fine woven linen, you shall make it.It shall be doubled into a square: a span shall be its length, and a span shall be its width.And you shall put settings of stones in it, four rows of stones: The first row shall be a sardius, a topaz, and an emerald; this shall be the first row;the second row shall be a turquoise, a sapphire, and a diamond;the third row, a jacinth, an agate, and an amethyst;and the fourth row, a beryl, an onyx, and a jasper. They shall be set in gold settings.And the stones shall have the names of the sons of Israel, twelve according to their names, like the engravings of a signet, each one with its own name; they shall be according to the twelve tribes.
