And Moses took the blood, sprinkled it on the people, and said, “This is the blood of the covenant which the Lord has made with you according to all these words.”
In the same manner He also took the cup after supper, saying, “This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me.”
The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
