Leviticus 17:2-6

2“Speak to Aaron, to his sons, and to all Bnei-Yisrael, and say to them: This is the word which Adonai has commanded.

3Anyone from the house of Israel who slaughters a bull, a lamb or a goat in the camp or outside the camp,

4but has not brought it to the entrance of the Tent of Meeting to offer it as a sacrifice to Adonai before the Tabernacle—let bloodguilt be charged to that man. He has shed blood—that man is to be cut off from among his people.

5Thus Bnei-Yisrael may bring their sacrifices that they were making in the open field to Adonai, at the entrance of the Tent of Meeting to the kohen, and offer them as sacrifices of fellowship offerings to Adonai.

6The kohen is to sprinkle the blood on the altar of Adonai at the entrance of the Tent of Meeting and burn up the fat as smoke for a soothing aroma to Adonai.
