Mark 14:24
This is my blood of the covenant, which is poured out for many, he said to them — this is my blood of the covenant echoes the Sinai covenant ratification (Exodus 24:8: this is the blood of the covenant that the Lord has made with you). The new covenant in Jeremiah 31:31–34 promised a new covenant to replace the one Israel broke. Poured out for many: the same ransom-for-many language as Mark 10:45 — the substitutionary giving of Jesus' life for many.
