Leviticus 16:2-4

Common English Bible

² Tell your brother Aaron that he cannot come whenever he wants into the holy area inside the inner curtain, to the front of the cover^[a] that is on the chest, or else he will die, because I am present^[b] in the cloud above the cover. ³ No, but Aaron must enter the holy area as follows: with a bull from the herd as a purification offering and a ram as an entirely burned offering. ⁴ Aaron must dress in a holy linen tunic and wear linen undergarments on his body. He must tie a linen sash around himself and wrap a linen turban around his head. These are holy clothes—Aaron will first bathe his body in water and then put them on.
