Today's Verse
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
Historical Context
Exodus 24 sits at the hinge of the book. Israel has been brought out of Egypt, led through the sea, fed with manna, and gathered at Sinai. In chapters 20 to 23 God has spoken: the Ten Commandments, then the body of case law known as the Book of the Covenant. Chapter 24 is the ratification. This is how the covenant becomes binding.
Moses writes the words down. He builds an altar with twelve stone pillars, one for each tribe, so the whole nation is represented at the foot of the mountain. Young men, not yet an ordained priesthood, offer burnt offerings and peace offerings. Then comes the strange and arresting act: half the blood is thrown against the altar, half is thrown on the people. The altar represents God. The people represent themselves. The same blood touches both. They are now bound together by it.
Ancient covenants were sealed in blood for a reason. To cut a covenant was to say: let what happened to this animal happen to me if I break my word. The blood was a sworn, visible, inescapable pledge. In the ancient Near East, treaties between a great king and a vassal people followed this pattern, and Sinai uses the form Israel would have recognized.
The people answer twice, and the second answer is fuller than the first: 'All that the LORD has spoken we will do, and we will be obedient.' They mean it. They will also break it, repeatedly, starting a few chapters later with a golden calf. The covenant at Sinai is real and good, but it exposes a problem it cannot solve: a sinful people cannot keep faith with a holy God.
Reflection
Fifteen centuries after Moses threw blood on the people, Jesus lifted a cup in a borrowed room and said, 'This is my blood of the covenant, which is poured out for many for the forgiveness of sins' (Matthew 26:28). Every man at that table knew Exodus 24. Jesus was not inventing a metaphor. He was telling them what He was about to do.
At Sinai, the blood of oxen bound Israel to God, and Israel could not keep the terms. At Calvary, the blood of the Son of God binds a new people to the Father, and the terms are kept by Christ Himself. He is both the sacrifice and the faithful partner. He obeys where we failed. He bleeds where we deserved to.
This matters because we are tempted, still, to answer like Israel: 'All that the LORD has spoken we will do.' We mean it on Sunday. By Tuesday we have broken it. If our standing with God rested on how well we kept our word to Him, we would have no standing at all. It rests instead on how perfectly He kept His word to us, in the body and blood of His Son.
So when you come to the Table, or hear the gospel preached, or read the words of institution, hear Moses behind them. Behold the blood of the covenant. Not oxen now, but the Lamb. Not a mountain you cannot climb, but a Savior who came down. Not a pledge you must keep, but a pledge He has kept for you.
And then live like someone the blood has touched. The covenant is not advice. It is a bond, and you belong to Him.
For Reflection
Where in your life are you still trying to earn a standing with God that His blood has already secured for you?
Prayer
Father, we thank You that You did not leave us at the foot of Sinai, trembling at a covenant we could not keep. You sent Your Son to shed His own blood, to bind us to You by a bond we could never forge ourselves. Teach us to rest in what Christ has done, and to walk in glad obedience as those who belong to You by blood. Keep us faithful to the covenant He has made. In Jesus' name, Amen.
