Exodus 28:6-14

⁶“They shall also make the ephod of gold, of blue and purple and scarlet material and fine twisted linen, the work of the skillful workman. ⁷It shall have two shoulder pieces joined to its two ends, that it may be joined. ⁸The skillfully woven band, which is on it, shall be like its workmanship, of the same material: of gold, of blue and purple and scarlet material and fine twisted linen. ⁹You shall take two onyx stones and engrave on them the names of the sons of Israel, ¹⁰six of their names on the one stone and the names of the remaining six on the other stone, according to their birth. ¹¹As a jeweler engraves a signet, you shall engrave the two stones according to the names of the sons of Israel; you shall set them in filigree settings of gold. ¹²You shall put the two stones on the shoulder pieces of the ephod, as stones of memorial for the sons of Israel, and Aaron shall bear their names before the Lord on his two shoulders for a memorial. ¹³You shall make filigree settings of gold, ¹⁴and two chains of pure gold; you shall make them of twisted cordage work, and you shall put the corded chains on the filigree settings.
