Leviticus 17:1-5,10-12

“The Lord said to Moses, ‘Speak to Aaron and his sons and to all the Israelites and say to them: “This is what the Lord has commanded: Any Israelite who sacrifices an ox, a lamb or a goat in the camp or outside of it instead 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 man shall be considered guilty of bloodshed; he has shed blood and must be cut off from his people. This 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.” ‘ ”

…

” ‘Any Israelite or any alien living among them who eats any blood – I will set my face against that person who eats blood and will cut him off from his people. For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life. Therefore I say to the Israelites, “None of you may eat blood, nor may an alien living among you eat blood.” ‘ “
