Exodus 28:40

38It shall be on Aaron’s forehead, and Aaron shall bear the iniquity of the holy things, which the children of Israel shall make holy in all their holy gifts; and it shall be always on his forehead, that they may be accepted before the LORD.

39You shall weave the tunic with fine linen. You shall make a turban of fine linen. You shall make a sash, the work of the embroiderer.

40“You shall make tunics for Aaron’s sons. You shall make sashes for them. You shall make headbands for them, for glory and for beauty.

41You shall put them on Aaron your brother, and on his sons with him, and shall anoint them, and consecrate them, and sanctify them, that they may minister to me in the priest’s office.

42You shall make them linen pants to cover their naked flesh. They shall reach from the waist even to the thighs.
