Leviticus 17:14-16 English Standard Version (ESV)

14. For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.

15. And every person who eats what dies of itself or what is torn by beasts, whether he is a native or a sojourner, shall wash his clothes and bathe himself in water and be unclean until the evening; then he shall be clean.

16. But if he does not wash them or bathe his flesh, he shall bear his iniquity.”
