And Moses took the blood and sprinkled on the people, and said, Behold, the blood of the covenant which Jehovah has cut with you concerning these words.
Then Jesus said to them, Truly, truly, I say to you, If you do not eat the flesh of the Son of Man, and drink His blood, you do not have life in yourselves.
The cup of blessing that we bless, is it not a communion of the blood of Christ? The bread which we break, is it not a communion of the body of Christ?
In the same way the cup also, after the order to eat supper, He said, This cup is the New Covenant in My blood; as often as you drink, do this in remembrance of Me.
