Exodus 28:9-21

9You shall take two onyx stones and engrave on them the names of the [twelve] sons of Israel,

10six of their names on one stone and the remaining six names on the other stone, arranged in the order of their births.

11With the work of a jeweler, like the engravings of a signet, you shall engrave the two stones according to the names of the sons of Israel. You shall have them set in filigree [settings] of gold.

12You shall put the two stones on the [two] shoulder pieces of the ephod [of the high priest], as memorial stones for Israel; and Aaron shall bear their names on his two shoulders as a memorial before the Lord.

13You shall make filigree [settings] of gold,

14and you are to make two chains of pure gold like twisted cords, and fasten the corded chains to the settings.

15“You are to make a breastpiece of judgment, the work of a skilled and talented craftsman; like the work of the ephod you shall make it: of gold, of blue, purple, and scarlet fabric and of fine twisted linen.

16The breastpiece shall be square and folded double; a span [about nine inches] in length and a span in width.

17You shall mount on it four rows of stones: the first row shall be a row of ruby, topaz, and emerald;

18the second row a turquoise, a sapphire, and a diamond;

19the third row a jacinth, an agate, and an amethyst;

20and the fourth row a beryl and an onyx and a jasper; they shall be set in gold filigree.

21The [engraved] stones shall be twelve, according to the names of [the twelve tribes of] the sons of Israel; they shall be like the engravings of a signet, each with its name for the twelve tribes.
