Leviticus 17:3-7

3Any Israelite who sacrifices an ox, a lamb or a goat in the camp or outside of it

4instead of bringing it to the entrance to the tent of meeting to present it as an offering to the Lord in front of the tabernacle of the Lord—that person shall be considered guilty of bloodshed; they have shed blood and must be cut off from their people.

5This is so the Israelites will bring to the Lord the sacrifices they are now making in the open fields. They must bring them to the priest, that is, to the Lord, at the entrance to the tent of meeting and sacrifice them as fellowship offerings.

6The priest is to splash the blood against the altar of the Lord at the entrance to the tent of meeting and burn the fat as an aroma pleasing to the Lord.

7They must no longer offer any of their sacrifices to the goat idols to whom they prostitute themselves. This is to be a lasting ordinance for them and for the generations to come.’
