Leviticus 16:2-4

Expanded Bible

² The Lord said to him, “Tell your brother Aaron that there are times when he cannot go ·behind [inside] the curtain ·into the Most Holy Place [^Lbefore the mercy seat/atonement cover; Ex. 25:17–22] where the Ark is. If he goes in when I appear in a cloud over the ·lid on the Ark [mercy seat; atonement cover], he will die.

³ “This is how Aaron may enter the Most Holy Place: Before he enters, he must offer a bull for a ·sin [or purification; 4:3] offering and a ·male sheep [ram] for a whole burnt offering [1:1–17]. ⁴ He must put on the holy linen inner robe [Ex. 28:39–41], with the linen underclothes [Ex. 28:42–43] next to his body. His belt will be the cloth belt [sash], and he will wear the linen turban. These are holy clothes, so he must bathe his body in water before he puts them on.
