Leviticus 17:2-6

“Speak to Aaron and to his sons and to all the sons of Israel, and say to them, ‘This is what the Lord has commanded, saying,

“Anyone from the house of Israel who slaughters an ox, a lamb, or a goat in the camp, or slaughters it outside the camp,

and has not brought it to the doorway of the tent of meeting to present it as an offering to the Lord in front of the tabernacle of the Lord, bloodshed is to be counted against that person. He has shed blood, and that person shall be cut off from among his people.

This shall be done so that the sons of Israel will bring their sacrifices which they were sacrificing in the open field—so that they will bring them to the Lord at the doorway of the tent of meeting to the priest, and sacrifice them as sacrifices of peace offerings to the Lord.

The priest shall sprinkle the blood on the altar of the Lord at the doorway of the tent of meeting, and offer up the fat in smoke as a soothing aroma to the Lord.
