Exodus 28:4, 15

These are the garments they are to make: a breastpiece, an ephod, a robe, a woven tunic, a turban and a sash. They are to make these sacred garments for your brother Aaron and his sons, so they may serve me as priests.

“Fashion a breastpiece for making decisions—the work of skilled hands. Make it like the ephod: of gold, and of blue, purple and scarlet yarn, and of finely twisted linen.
