Leviticus 17:3-5

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

4and 1has not brought it to the doorway of the tent of meeting to present it as an offering to the Lord in front of the 2tabernacle 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.

5This shall be done so that the sons of Israel will bring their sacrifices which they were sacrificing 3in 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.
