Exodus 35:9

And rams' skins dyed red, and badgers' skins, and shittim wood,

And thou shalt take two onyx stones, and grave on them the names of the children of Israel: Six of their names on one stone, and the other six names of the rest on the other stone, according to their birth. With 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 ouches of gold. And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial unto the children of Israel: and Aaron shall bear their names before the LORD upon his two shoulders for a memorial. And thou shalt make ouches of gold; And two chains of pure gold at the ends; of wreathed work shalt thou make them, and fasten the wreathed chains to the ouches. And thou shalt make the breastplate of judgment with cunning 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. Foursquare it shall be being doubled; a span shall be the length thereof, and a span shall be the breadth thereof. And 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. And the second row shall be an emerald, a sapphire, and a diamond. And the third row a ligure, an agate, and an amethyst. And the fourth row a beryl, and an onyx, and a jasper: they shall be set in gold in their inclosings. And 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.

And they wrought onyx stones inclosed in ouches of gold, graven, as signets are graven, with the names of the children of Israel. And he put them on the shoulders of the ephod, that they should be stones for a memorial to the children of Israel; as the LORD commanded Moses. And he made the breastplate of cunning work, like the work of the ephod; of gold, blue, and purple, and scarlet, and fine twined linen. It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled. And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row. And the second row, an emerald, a sapphire, and a diamond. And the third row, a ligure, an agate, and an amethyst. And the fourth row, a beryl, an onyx, and a jasper: they were inclosed in ouches of gold in their inclosings. And the stones were according to the names of the children of Israel, twelve, according to their names, like the engravings of a signet, every one with his name, according to the twelve tribes.
