Vayikra 16:2-4

Orthodox Jewish Bible

² And Hashem said unto Moshe, Speak unto Aharon thy brother, that he come not at any time into HaKodesh within the Parochet (curtain) before the Kapporet, which is upon the Aron; that he die not; for I will appear in the Anan upon the Kapporet.

³ Thus shall Aharon come into HaKodesh: with a young bull for a chattat, and a ram for an olah (burnt offering).

⁴ He shall put on the Kesones Bahd Kodesh (holy linen tunic [see Yn 19:23 on Moshiach’s Kesones, the day kapporah was made by the Kohen L’Olahm al Divrati Melki-Tzedek—Ps 110:4]), and he shall have the Mikhnesei Bahd (linen breeches) upon his basar, and shall be girded with a Avnet Bahd (linen sash), and with the Mitznefet Bahd (linen turban) shall he be attired; these are Bigdei Kodesh; therefore shall he immerse his basar in mayim, and so put them on.
