Exodus 28:17-21

17You shall 1mount on it four rows of stones; the first row shall be a row of ruby, topaz and emerald;

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

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

20and the fourth row a beryl and an onyx and a jasper; they shall be 2set in gold filigree.

21The stones shall be according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a seal, each 3according to his name for the twelve tribes.
