Exodus 24
Exodus 24 is the ratification of the Sinai covenant, and its ceremony is among the most solemn in Scripture. Moses, Aaron, Nadab, Abihu, and seventy elders go up the mountain and see the God of Israel — and the description is spare and astonishing: under His feet something like a pavement of sapphire, clear as the sky itself. They eat and drink in His presence without being destroyed. Moses writes down all the Lord's words, builds an altar at the base of the mountain with twelve pillars for the twelve tribes, and the young men offer burnt offerings. He reads the Book of the Covenant to the people, who respond: we will do everything the Lord has said. Moses takes the blood, sprinkles half on the altar and half on the people: this is the blood of the covenant. Then Moses goes up into the cloud for forty days and forty nights to receive the stone tablets. The blood of the covenant, the communal meal in God's presence, and the mediation of Moses all find their fulfillment in the Last Supper, where Jesus takes the cup and says: this is my blood of the covenant, poured out for many — quoted directly in Matthew 26:28. The ceremony here is the shadow; the cross is the substance.
Exodus 24:1
Then he said to Moses: come up to the Lord, you and Aaron, Nadab and Abihu, and seventy of the elders of Israel. You are to worship at a distance. The covenant ratification ceremony begins with a specific invitation: Moses, Aaron, Aaron's two sons who will later die for offering unauthorized fire (Leviticus 10), and seventy elders — the same seventy who represent the fullness of Israel at Sinai. The invitation comes in grades of proximity: Moses goes nearest, the priests and elders at a middle distance, the people at the base. The graduated approach to the holy that has characterized the Sinai narrative — from the boundary around the mountain to the thresholds of the tabernacle — is here enacted in human bodies ascending the mountain. Hebrews 10:22 says let us draw near to God with a sincere heart — the drawing near that was gradual and partial at Sinai becomes complete in Christ.
Exodus 24:2
But Moses alone is to approach the Lord; the others must not come near. And the people may not come up with him. Moses' singular proximity to God is maintained throughout the covenant ceremony. The others worship at a distance; Moses alone approaches the Lord. The distance is not punishment but protection — the holiness of God is dangerous to those who are not prepared or authorized for full proximity. Numbers 12:6–8 captures the uniqueness of Moses' access: with my servant Moses I speak face to face, clearly and not in riddles. Hebrews 7:25 says Christ always lives to intercede — the singular mediatorial access that Moses had at Sinai finds its permanent fulfillment in the one who intercedes without limit, without distance, and without the risk of death from proximity.
Exodus 24:3
When Moses came and told the people all the Lord's words and laws, they responded with one voice: everything the Lord has said we will do. The covenant acceptance in verse 3 is unanimous and vocal: one voice, everything. The response is the community's formal acceptance of the covenant terms laid out in Exodus 20–23. The recitation of all the Lord's words before the acceptance is significant: consent must be informed. The people are not agreeing to unspecified obligations but to the specific words they have just heard. Acts 2:37 records the crowd asking what shall we do in response to Peter's preaching — the covenant response of Exodus 24:3 is the pattern for every subsequent covenant-responsive community. Hearing the word and responding with communal commitment is the basic shape of covenant entry.
