Exodus

⁹And thou shalt take two onyx stones, and grave on them the names of the children of Israel: ¹⁰six of their names on the one stone, and the names of the six that remain 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, according to the names of the children of Israel: thou shalt make them to be enclosed in ouches of gold. ¹²And thou shalt put the two stones upon the shoulderpieces of the ephod, to be stones of memorial for the children of Israel: and Aaron shall bear their names before the Lord upon his two shoulders for a memorial. ¹³And thou shalt make ouches of gold: ¹⁴and two chains of pure gold; like cords shalt thou make them, of wreathen work: and thou shalt put the wreathen chains on the ouches. ¹⁵And thou shalt make a breastplate of judgment, the work of the cunning workman; like the work of the ephod thou shalt make it; of gold, of blue, and purple, and scarlet, and fine twined linen, shalt thou make it.
