Leviticus 17:3-4

3If any one of the house of Israel kills an ox or a lamb or a goat in the camp, or kills it outside the camp,

4and does not bring it to the entrance of the tent of meeting to offer it as a gift to the Lord in front of the tabernacle of the Lord, bloodguilt shall be imputed to that man. He has shed blood, and that man shall be cut off from among his people.
