Exodus 39:27-29 - The Other Priestly Garments
27 And they made the tunics of fine linen, a weaver's work, for Aaron and for his sons, 28 and the turban of fine linen and the headdresses of the headbands of fine linen and undergarments of the linen cloth, finely twisted, 29 and the sash of finely twisted linen and blue and purple and crimson [yarns], the work of an embroiderer, as Yahweh had commanded Moses.
