Leviticus 16:4

1 And Jehovah speaketh unto Moses, after the death of the two sons of Aaron, in their drawing near before Jehovah, and they die;

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.

5 `And from the company of the sons of Israel he taketh two kids of the goats for a sin-offering, and one ram for a burnt-offering;

6 and Aaron hath brought near the bullock of the sin-offering which is his own, and hath made atonement for himself, and for his house;

7 and he hath taken the two goats, and hath caused them to stand before Jehovah, at the opening of the tent of meeting.
