Leviticus 16:2-4

Young's Literal Translation

² yea, Jehovah saith unto Moses, `Speak unto Aaron thy brother, and he cometh not in at all times unto the sanctuary within the vail, unto the front of the mercy-seat, which [is] upon the ark, and he dieth not, for in a cloud I am seen upon the mercy-seat.

³ `With this doth Aaron come in unto the sanctuary; with a bullock, a son of the herd, for a sin-offering, and a ram for a burnt-offering;

⁴ a holy linen coat he putteth on, and linen trousers are on his flesh, and with a linen girdle he girdeth himself, and with a linen mitre he wrappeth himself up; they [are] holy garments; and he hath bathed with water his flesh, and hath put them on.
