Exodus 28:42-43

Darby Translation

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.
