Leviticus 16:2-4

New International Reader's Version

² The Lord said to Moses, “Speak to your brother Aaron. Tell him not to come into the Most Holy Room just anytime he wants to. Tell him not to come behind the curtain in front of the cover of the ark. The cover is the place where sin is paid for. If he comes behind the curtain, he will die. That is because I appear in the cloud over the cover.

³ “Aaron must not enter the area of the Most Holy Room without bringing a sacrifice. He must bring a young bull for a sin offering. He must also bring a ram for a burnt offering. ⁴ He must put on the sacred inner robe made out of linen. He must wear linen underwear next to his body. He must tie the linen belt around him. And he must put the linen turban on his head. Those are sacred clothes. So he must take a bath before he puts them on.
