Exodus

⁸And thou shalt bring his sons, and put coats upon them. ⁹And thou shalt gird them with girdles, Aaron and his sons, and bind headtires on them: and they shall have the priesthood by a perpetual statute: and thou shalt consecrate Aaron and his sons. ¹⁰And thou shalt bring the bullock before the tent of meeting: and Aaron and his sons shall lay their hands upon the head of the bullock. ¹¹And thou shalt kill the bullock before the Lord, at the door of the tent of meeting. ¹²And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger; and thou shalt pour out all the blood at the base of the altar. ¹³And thou shalt take all the fat that covereth the inwards, and the caul upon the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. ¹⁴But the flesh of the bullock, and its skin, and its dung, shalt thou burn with fire without the camp: it is a sin offering.
