And Moses took the blood and threw it on the people and said, “Behold the blood of the covenant that the Lord has made with you in accordance with all these words.”
In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.”
The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?
