Leviticus 16:2-4

Revised Standard Version Catholic Edition

² and the Lord said to Moses, “Tell Aaron your brother not to come at all times into the holy place within the veil, before the mercy seat which is upon the ark, lest he die; for I will appear in the cloud upon the mercy seat. ³ But thus shall Aaron come into the holy place: with a young bull for a sin offering and a ram for a burnt offering. ⁴ He shall put on the holy linen coat, and shall have the linen breeches on his body, be girded with the linen girdle, and wear the linen turban; these are the holy garments. He shall bathe his body in water, and then put them on.
