Leviticus 16:20-22, 17:10-12
“When Aaron has finished making atonement for the Most Holy Place, the Tent of Meeting and the altar, he shall bring forward the live goat. He is to lay both hands on the head of the live goat and confess over it all the wickedness and rebellion of the Israelites-all their sins-and put them on the goat’s head. He shall send the goat away into the desert in the care of a man appointed for the task. The goat will carry on itself all their sins to a solitary place; and the man shall release it in the desert.
“‘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.”
Matthew 26:26–28
While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, “Take and eat; this is my body.”
Then he took the cup, gave thanks and offered it to them, saying, “Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins.
