Exodus 28:13

¹¹It shall be the work of the stone engraver’s art; as the graving of a seal thou shalt engrave the two stones with the names of the children of Israel.

¹²And thou shalt put the two stones on the shoulders of the shoulder piece: they are memorial stones for the children of Israel: and Aaron shall bear the names of the children of Israel before the Lord on his two shoulders, a memorial for them.

— Exodus 28:13 —

¹⁴and thou shalt make two fringes of pure gold, variegated with flowers, wreathen work; and thou shalt put the wreathen fringes on the circlets, fastening them on their shoulder pieces in front.

¹⁵And thou shalt make the oracle of judgment, the work of the embroiderer: in keeping with the ephod, thou shalt make it of gold, and blue and purple, and spun scarlet, and fine linen spun.
