Exodus 28:9-21

9And thou shalt take two onyx stones, and engrave on them the names of the children of Israel: 10Six of their names on one stone, and the six names of the rest on the other stone, according to their birth. 11With the work of an engraver in stone, like the engravings of a signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in settings of gold. 12And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial to the children of Israel: and Aaron shall bear their names before the LORD upon his two shoulders for a memorial. 13And thou shalt make settings of gold; 14And two chains of pure gold at the ends; of braided work shalt thou make them, and fasten the braided chains to the settings.

15And thou shalt make the breastplate of judgment with skilful work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen, shalt thou make it. 16Foursquare it shall be being doubled; a span shall be its length, and a span shall be its breadth. 17And thou shalt set in it settings of stones, even four rows of stones: the first row shall be a sardius, a topaz, and a carbuncle: this shall be the first row.12 18And the second row shall be an emerald, a sapphire, and a diamond. 19And the third row a ligure, an agate, and an amethyst. 20And the fourth row a beryl, and an onyx, and a jasper: they shall be set in gold in their inclosings.3 21And the stones shall be with the names of the children of Israel, twelve, according to their names, like the engravings of a signet; every one with his name shall they be according to the twelve tribes.
