Exodus 28:41-43

Darby Translation

⁴¹ And thou shalt clothe with them Aaron thy brother, and his sons with him; and shalt anoint them, and consecrate them, and hallow them, that they may serve me as priests.

⁴² And thou shalt make them linen trousers to cover the flesh of nakedness; from the loins even to the hips shall they reach.

⁴³ And they shall be upon Aaron and his sons when they enter into the tent of meeting, or when they come near to the altar to serve in the sanctuary; that they may not bear iniquity and die—an everlasting statute for him and his seed after him.
