Exodus 28:4, 15

And these are the garments which they shall make: a breastplate, an ephod, a robe, a skillfully woven tunic, a turban, and a sash. So they shall make holy garments for Aaron your brother and his sons, that he may minister to Me as priest.

“You shall make the breastplate of judgment. Artistically woven according to the workmanship of the ephod you shall make it: of gold, blue, purple, and scarlet thread, and fine woven linen, you shall make it.
