From Exodus to the Upper Room: The Blood Covenant Fulfilled in Christ

How the Mosaic Covenant in Exodus 24 foreshadows and finds its fulfillment in the New Covenant established by Jesus in Luke 22

In our previous studies, we examined the Mosaic Covenant's establishment and the symbolism of the twelve pillars. Now we reach the climax of our series: discovering how this ancient covenant points directly to Jesus and the New Covenant sealed with His blood.

Exodus 24

Old Covenant
Blood of Oxen

Luke 22

New Covenant
Blood of Christ

1. The Central Act: A Covenant Ratified with Blood

Exodus 24 (Old Covenant)

Moses takes the blood of sacrificed oxen, sprinkles half on the altar (representing God) and half on the people, saying:

"This is the blood of the covenant that the LORD has made with you" Exodus 24:8
Luke 22 (New Covenant)

Jesus takes the cup of wine and says:

"This cup that is poured out for you is the new covenant in my blood" Luke 22:20

Similarity: Both covenants are formally established and sealed with blood.

Contrast/Fulfillment: The blood of animals is replaced by the blood of Christ Himself. His one-time, perfect sacrifice replaces the repeated, imperfect animal sacrifices (Hebrews 9:18-22).

2. The "Twelve" as Representatives

Exodus 24

Moses builds twelve pillars representing the twelve tribes of Israel, the people of the Old Covenant.

The pillars stood as silent witnesses to the covenant between Yahweh and His people.

Luke 22

Jesus institutes the New Covenant with His twelve apostles present. He tells them:

"You are those who have stayed with me in my trials, and I assign to you a kingdom, just as my Father assigned to me, that you may eat and drink at my table in my kingdom and sit on thrones judging the twelve tribes of Israel" Luke 22:28-30

Similarity: The "twelve" represent the entirety of the covenant people.

Contrast/Fulfillment: The twelve stone pillars (inanimate objects) are replaced by the twelve apostles (living witnesses). They become the foundation of the new, spiritual Israel (Ephesians 2:20).

3. Obedience to the Covenant Terms

Exodus 24

The people unanimously pledge their obedience, declaring:

"All that the LORD has spoken we will do, and we will be obedient" Exodus 24:7

This covenant was based on law and external obedience.

Luke 22

The New Covenant, prophesied in Jeremiah 31:31-34, is based on internal transformation:

"I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people" Jeremiah 31:33

It is characterized by forgiveness of sins and the law written on hearts.

Similarity: Both covenants call for a faithful response from the people.

Contrast/Fulfillment: The Old Covenant revealed human inability to keep the law. The New Covenant provides the means for obedience through the Holy Spirit and the forgiveness of sins.

4. The Communal Meal in God's Presence

Exodus 24

After the blood is sprinkled, Moses, Aaron, Nadab, Abihu, and the seventy elders of Israel go up and eat a communal meal in God's presence:

"They beheld God, and ate and drank" Exodus 24:11

This sacred meal celebrated the newly established relationship between God and His people.

Luke 22 & 1 Corinthians

Jesus institutes the Lord's Supper as the new covenant meal:

"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? For we being many are one bread, and one body: for we are all partakers of that one bread" 1 Corinthians 10:16-17

Similarity: Both covenants are celebrated with a sacred meal in God's presence.

Contrast/Fulfillment: The temporary fellowship meal of Exodus becomes the ongoing sacrament of Communion, where believers continually remember and participate in Christ's sacrifice until He returns.

Summary: Old Covenant to New Covenant

Feature Exodus 24 (Old Covenant) Luke 22 (New Covenant)

Mediator Moses, the servant Jesus, the Son
Representatives 12 Stone Pillars (Tribes) 12 Apostles (New Israel)
Basis Law & Obedience Pledge Grace & Internal Transformation
Ratifying Meal Communal Meal on the Mountain The Lord's Supper (Communion)
Result Revealed sin, brought condemnation Brings forgiveness, enables obedience
"Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant." Hebrews 9:15

Application for Today's Believers

Understanding this covenant fulfillment transforms how we approach our faith:

1. Communion becomes profoundly meaningful - When we take the bread and cup, we're not just remembering a historical event; we're participating in the fulfilled covenant meal that connects us directly to God's redemptive plan from Exodus forward.

2. Our identity is secure - Just as the twelve pillars represented all Israel, we are represented in Christ. Our standing before God isn't based on our ability to keep the law but on Christ's perfect obedience and sacrifice.

3. Obedience flows from transformation - The New Covenant doesn't abolish God's standards but empowers us to live them out from renewed hearts, by the Spirit's power.

"And by that will we have been sanctified through the offering of the body of Jesus Christ once for all." Hebrews 10:10

As we conclude this series on the Mosaic Covenant, we see with clarity how the entire Old Testament points to Christ. The blood sprinkled in Exodus, the pillars representing the tribes, the covenant meal—all find their ultimate meaning and fulfillment in Jesus and the New Covenant established through His blood.

Reflection Question: How does understanding the connection between Exodus 24 and Luke 22 deepen your appreciation for Communion and your identity as part of God's covenant people?
