Exodus 28:16

You shall make settings of gold,

and two chains of pure gold; you shall make them like cords of braided work. You shall put the braided chains on the settings.

“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.

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

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

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