Exodus 28:42-43

Douay-Rheims 1899 American Edition

⁴² Thou shalt make also linen breeches, to cover the flesh of their nakedness from the reins to the thighs:

⁴³ And Aaron and his sons shall use them when they shall go in to the tabernacle of the testimony, or when they approach the altar to minister in the sanctuary, lest being guilty of iniquity they die. It shall be a law for ever to Aaron, and to his seed after him.
