What Did Jesus Mean by “This Is My Blood of the Covenant”? Understanding the Last Supper
On the night before His crucifixion, Jesus took a cup and spoke words that would echo through history:
“For this is my blood of the covenant, which is poured out for many for the forgiveness of sins.” (Matthew 26:28, ESV)
These were not spontaneous poetic words. They were deliberate covenant language. They reached backward to Sinai. They fulfilled prophecy. They anticipated the cross. And they explained the meaning of His death before it happened.
As we continue tracing The Blood in Scripture, we now stand in the upper room. The Lamb announced in John 1 is about to be sacrificed. But before the blood is shed, Jesus explains what it will accomplish.
Direct Answer: What Did Jesus Mean by “My Blood of the Covenant”?
- He was identifying His death as covenant-establishing.
- He was fulfilling the blood covenant of Exodus 24.
- He was inaugurating the New Covenant promised in Jeremiah 31.
- His blood would secure forgiveness of sins.
- His death would accomplish what animal sacrifices never could.
It was covenant fulfillment.
Why Does Jesus Use Covenant Language?
Jesus did not invent the phrase “blood of the covenant.” It appears first in Exodus 24. After the LORD gave the Law at Sinai, Moses built an altar and offered sacrifices. Then we read:
“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.’” (Exodus 24:8, ESV)
Blood ratified the covenant. It signified that the agreement between God and His people was solemn, binding, and secured through sacrifice.
When Jesus says, “This is my blood of the covenant,” He is consciously echoing Sinai. But this time, the mediator is not Moses. The sacrifice is not a bull. The blood is His own.
What Was Happening at the Last Supper?
The setting was Passover (Luke 22:15). Israel was remembering deliverance from Egypt — when lambs were slain and blood shielded homes from judgment.
Jesus takes bread and identifies it with His body. He takes the cup and identifies it with His blood.
“And likewise the cup after they had eaten, saying, ‘This cup that is poured out for you is the new covenant in my blood.’” (Luke 22:20, ESV)
The Passover meal becomes the moment of reinterpretation. The lamb of Exodus pointed forward. Now the Lamb Himself speaks.
Jesus announces the greater deliverance.
What Is the New Covenant?
Centuries earlier, Jeremiah had prophesied:
“Behold, the days are coming, declares the LORD, when I will make a new covenant with the house of Israel… For I will forgive their iniquity, and I will remember their sin no more.” (Jeremiah 31:31, 34, ESV)
The Old Covenant exposed sin. It required continual sacrifices. It revealed God’s holiness.
The New Covenant would provide internal transformation and complete forgiveness.
When Jesus speaks of His blood as covenant blood, He is announcing that Jeremiah’s promise is being fulfilled.
The New Covenant removes it.
What Does “Poured Out for Many” Mean?
Jesus says His blood is “poured out for many for the forgiveness of sins.”
The phrase “poured out” reflects sacrificial imagery. In the Old Testament, blood was poured out at the base of the altar (Leviticus 4:7).
The language “for many” echoes Isaiah 53:
“He bore the sin of many.” (Isaiah 53:12, ESV)
Jesus is identifying Himself as the Servant who bears iniquity.
This is not language of potential atonement only. It is substitutionary language. His blood is shed on behalf of others.
How Is This Different from the Blood of Bulls and Goats?
The Old Covenant sacrifices were repeated. They pointed forward but did not perfect the conscience.
Hebrews later explains:
“For if the blood of goats and bulls… sanctify for the purification of the flesh, how much more will the blood of Christ… purify our conscience from dead works to serve the living God.” (Hebrews 9:13–14, ESV)
Jesus’ blood accomplishes inward cleansing. It secures eternal redemption.
Christ’s blood accomplishes.
What Does This Mean for the Forgiveness of Sins?
Jesus explicitly connects His blood with forgiveness.
Forgiveness in Scripture is not sentimental. It is judicial. Sin creates guilt. Guilt demands justice. Blood signifies life given in place of another.
Under the New Covenant, forgiveness is secured not through repeated sacrifice, but through one offering once for all.
The cross is not merely an example of love. It is the means of pardon.
How Does the Last Supper Connect to the Entire Blood Theme?
- Genesis 3 — covering through death.
- Abraham — substitute provided.
- Passover — lamb shields from judgment.
- Sinai — covenant ratified by blood.
- Day of Atonement — sin transferred and removed.
- Isaiah 53 — Servant bears iniquity.
- John 1 — the Lamb revealed.
- The Last Supper — the Lamb explains His sacrifice.
Each step leads here. The covenant is no longer written merely on stone. It will be sealed in blood.
Why Does This Matter Today?
Every time believers partake of the Lord’s Supper, they remember that redemption rests on covenant blood.
Salvation is not grounded in moral reform or religious ritual. It rests in Christ’s once-for-all sacrifice.
The New Covenant promises:
- Forgiveness.
- Reconciliation.
- Internal transformation.
- Access to God.
All secured through the blood of Christ.
Key Truths from the Last Supper
