Exodus 28:42-43

World English Bible

⁴² You shall make them linen pants to cover their naked flesh. They shall reach from the waist even to the thighs. ⁴³ They shall be on Aaron and on his sons, when they go in to the Tent of Meeting, or when they come near to the altar to minister in the holy place, that they don’t bear iniquity, and die. This shall be a statute forever to him and to his offspring after him.
