Exodus 28:6-14

⁶ And they shall make the ephod of gold, of blue, and purple, scarlet, and fine twined linen, the work of the skilful workman. ⁷ It shall have two shoulder-pieces joined to the two ends thereof, that it may be joined together. ⁸ And the skilfully woven band, which is upon it, wherewith to gird it on, shall be like the work thereof [and] of the same piece; of gold, of blue, and purple, and scarlet, and fine twined linen. ⁹ And thou shalt take two onyx stones, and grave on them the names of the children of Israel: ¹⁰ six of their names on the one stone, and the names of the six that remain on the other stone, according to their birth. ¹¹ With 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 inclosed in settings of gold. ¹² And thou shalt put the two stones upon the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel: and Aaron shall bear their names before Jehovah upon his two shoulders for a memorial. ¹³ And thou shalt make settings of gold, ¹⁴ and two chains of pure gold; like cords shalt thou make them, of wreathen work: and thou shalt put the wreathen chains on the settings.
