Leviticus 16:2-4

International Standard Version

² The Lord told Moses, “Remind^[a] your brother Aaron that at no time is he to enter the sacred place from the room that contains the curtain into the presence of the Mercy Seat^[b] on top of the ark. Otherwise, he’ll die, because I will appear in a cloud at the Mercy Seat. ³ Aaron is to enter the sacred place with a young bull for a sin offering and a ram for a whole burnt offering. ⁴ He is to wear a sacred linen tunic and linen undergarments that will cover his genitals. He is to clothe himself with a sash and wrap his head with a linen turban. Because they are sacred garments, he is to wash himself with water before putting them on.”
