Exodus 28:39-42
39 “Weave the tunic of fine linen and make the turban of fine linen. The sash is to be the work of an embroiderer.
40 Make tunics, sashes and headbands for Aaron’s sons, to give them dignity and honor.
41 After you put these clothes on your brother Aaron and his sons, anoint and ordain them. Consecrate them so they may serve me as priests.
42 “Make linen undergarments as a covering for the body, reaching from the waist to the thigh.
