Matthew 26:28
For this is my blood of the covenant, which is poured out for many for the forgiveness of sins. The new covenant language of the cup: my blood of the covenant echoes Exodus 24:8 (Moses sprinkled the blood on the people and said, this is the blood of the covenant). The poured out for many for the forgiveness of sins is the ransom-for-many of Matthew 20:28 applied to the cup: the blood that Jesus is about to pour out is the covenant's blood that produces the forgiveness that the whole sacrifice system of Leviticus anticipated.
