Leviticus 17:9-11

New Century Version

⁹ that person must take his sacrifice to the entrance of the Meeting Tent to offer it to the Lord. If he does not do this, he must be cut off from the people.

¹⁰ “‘I will be against any citizen of Israel or foreigner living with you who eats blood. I will cut off that person from the people. ¹¹ This is because the life of the body is in the blood, and I have given you rules for pouring that blood on the altar to remove your sins so you will belong to the Lord. It is the blood that removes the sins, because it is life.
