Exodus 28:17

15“You shall make a breastplate of judgment, the work of the skillful workman; like the work of the ephod you shall make it; of gold, of blue, and purple, and scarlet, and fine twined linen, you shall make it.

16It shall be square and folded double; a span shall be its length, and a span its width.

17You shall set in it settings of stones, four rows of stones: a row of ruby, topaz, and beryl shall be the first row;

18and the second row a turquoise, a sapphire, and an emerald;

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