Exodus 28:9

⁷  It shall have the two shoulderpieces thereof joined at the two edges thereof; and so it shall be joined together.

⁸  And the curious girdle of the ephod, which is upon it, shall be of the same, according to the work thereof; even 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 one stone, and the other six names of the rest 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 with the names of the children of Israel: thou shalt make them to be set in ouches of gold.
