Exodus 24 brings the Sinai covenant to its formal ratification. The words, laws, and covenant terms that God spoke through Moses in chapters 19–23 have been given. Now they must be accepted, written, sealed in sacrifice, and enacted in worship. Ancient Near Eastern suzerainty treaties — the kind through which a great king established binding obligations with a vassal people — followed a recognizable pattern: public proclamation, formal assent, inscribed record, and covenant-confirming ceremony. Exodus 24 follows that pattern while transcending it. What happens at Sinai is not merely a political alliance but the constitution of a people before a holy God. Every element of the chapter carries weight: verbal commitment, written record, blood ceremony, a shared meal before God on the mountain, and a solitary ascent into the divine cloud that the watching people below could only describe as devouring fire.
Covenant Ratified on the Mountain
Main Highlights
- Moses writes the covenant words, reads them publicly, and the people pledge twice: "All that the LORD has spoken we will do."
- Blood is divided between the altar and the people — binding both God's side and Israel's side of the covenant under the same sacrifice.
- Seventy-four leaders ascend the mountain, see God, and eat and drink before Him without being destroyed — a breathtaking picture of covenant fellowship.
- Moses enters the glory cloud alone for forty days, receiving the detailed tabernacle blueprints while the people below can only see what looks like devouring fire.
Moses Writes and the People Hear
The day before the formal ratification, Moses comes to the people and recounts all the words of the Lord and all the rules — the Ten Commandments, the altar instruction, and the detailed case laws of the Book of the Covenant. The people respond together and unanimously: "All the words that the Lord has spoken we will do." — Exodus 24:3 (ESV). This communal assent is not a formality. In the ancient world, covenant ratification required the formal, spoken acceptance of the vassal people. Israel is here making a binding public declaration before God and their community: we accept these terms. The pledge has legal weight, and all that follows rests upon it.
Moses then does something of enormous consequence — he writes all the words of the Lord. This is the first mention in Exodus of Moses committing God's spoken words to text. Brevard Childs, in his Exodus commentary (1974), observes that the written form of the covenant carries a permanence that oral tradition cannot. A covenant inscribed in text can be read aloud to future generations, consulted in disputes, and appealed to when memory fails. It is not enough that Israel heard the words; the words must now exist in a form that outlasts the hearing. Israel's relationship with God has a document — and that document becomes the foundation from which everything in the rest of the Pentateuch will be measured.
The Altar, the Pillars, and the Blood Ceremony
The next morning, Moses rises early. He builds an altar at the foot of the mountain — not on the summit, where the divine fire burns, but at the base, where the assembled people can witness what is done. Around the altar he sets up twelve pillars, one for each tribe of Israel. The number matters: this covenant is not made with Moses alone, not with a priestly class, not with a self-selected group. All twelve tribes are represented in the twelve stones — silent witnesses standing in the landscape of Sinai that all of Israel has entered this relationship.
Young men are appointed to offer burnt offerings and peace offerings on the altar. The burnt offering represents complete consecration — the entire animal given over to God in smoke. The peace offering is different in kind: part of it rises to God in fire, but part is returned to the worshippers for a shared meal. These are not offerings of desperation but of relationship — the Israelites approaching God not to appease wrath but to enter communion. Walter Kaiser Jr. observes that the combination of burnt offering and peace offering at the moment of covenant ratification signals both the gravity of the covenant being entered and the fellowship it creates. The altar receives the blood of both.
Moses divides the blood. Half he throws against the altar. Half he keeps in basins. He then does something the people could not have anticipated: he takes the Book of the Covenant and reads it aloud in the hearing of all the people. This second reading — after the covenant text has been written down — produces a second assent: "All that the Lord has spoken we will do, and we will be obedient." — Exodus 24:7 (ESV). Only after this second public confirmation, after the people have heard the full text of their obligations and repeated their pledge, does Moses take the remaining blood from the basins and throw it on the people:
"Behold the blood of the covenant that the Lord has made with you in accordance with all these words." — Exodus 24:8 (ESV)
The blood thrown on the people is not punishment — it is ratification. Nahum Sarna observes that in the ancient Near Eastern world, blood signified life. To sprinkle blood on both the altar (which represents God's presence) and the people is to bind them together in a shared life, under the same sacrificial act. Altar and people are now covered by the same blood. They are, in the most physical sense available in that world, in covenant together. Matthew Henry notes that this is the closest Old Testament parallel to what Jesus institutes at the Last Supper: "This is my blood of the covenant, which is poured out for many for the forgiveness of sins" (Matthew 26:28, ESV). The author of Hebrews quotes Exodus 24:8 directly in Hebrews 9:20 while expounding the new covenant. The phrase "blood of the covenant" — rare in the Old Testament — carries the full weight of Sinai each time it appears.
We find it significant that the blood goes on both sides. Not just the altar — the people too. Both God's side and Israel's side of the covenant table are marked by the same blood, the same sacrifice. That is a picture of mutual binding that the New Testament will press all the way to its conclusion: the same blood that ratified Sinai ratifies the new covenant, and it is poured out once, not divided.
Seventy-Four Before God
After the blood ceremony, something extraordinary happens. God issues a specific invitation to a specific group: Moses and Aaron, Aaron's sons Nadab and Abihu, and seventy of the elders of Israel are called to ascend the mountain and worship at a distance. They are not to come to the summit — that remains Moses' alone — but they are to come up, into a region of nearness that no ordinary Israelite will reach. They go.
And what they see there is almost beyond description:
"And they saw the God of Israel. There was under his feet as it were a pavement of sapphire stone, like the very heaven for clearness." — Exodus 24:10 (ESV)
The text does not describe God's face or form. What is glimpsed is the pavement beneath the divine throne — clarity like sky, color like sapphire, transparency like the open heaven. Whatever they see, they see God. Immediately the text adds the detail that changes the weight of the whole scene: "And he did not lay his hand on the chief men of the people of Israel; they beheld God, and ate and drank." — Exodus 24:11 (ESV). God did not destroy them. The fact that He did not is recorded because it cannot be taken for granted. The holy God whose descent on Sinai required the people to stay behind barriers on pain of death — this God allows seventy-four men to ascend and enter something close to His presence. They behold God. They eat. They drink. They are not consumed.
This scene is almost never discussed, and we think that is a significant omission. Seventy-four people go up the mountain and see God. They do not die. They eat a meal. Think about what is happening there: covenant ratification produces an invitation to a meal, in the presence of God, on a mountain that was roped off with a death penalty for touching its base two days ago. The progression is breathtaking. The text records it as a fact without elaboration, as if it is entirely possible — which of course it is, because God invited them. But the gap between "do not touch the mountain or you will die" and "they beheld God, and ate and drank" is exactly the gap that the whole book of Exodus is trying to close.
Douglas Stuart observes that this covenant meal on the mountain is one of the most extraordinary scenes in the entire Old Testament. A shared meal in the ancient world was itself a covenant act — to eat together was to be in relationship, to affirm trust and shared life. That Israel's elders eat and drink in the presence of God is not a casual detail; it is the goal that the entire Sinai structure — covenant, law, blood — has been designed to make possible. Fellowship with the holy God requires approach through proper means, but when those means are honored, fellowship is real. For one afternoon on the mountain, seventy-four leaders of Israel experience precisely what the covenant promises: life before God, without destruction. This meal looks forward to every covenant meal that follows — the Passover feasts, the peace offerings, and ultimately the final banquet of Revelation 19, at which the Lamb and His people eat together at the same table.
Into the Cloud
After the covenant meal, the seventy-four descend. Moses and Joshua begin a further ascent together. Moses tells the elders to stay and wait — Aaron and Hur will be with them to handle any disputes. Then Moses and Joshua climb higher still. At some point, Moses goes on alone.
The cloud of God's glory has been settled on the summit for six days. On the seventh day, God calls to Moses from within the cloud. Moses enters. To the people watching from the camp far below, the sight is terrifying: "And the appearance of the glory of the Lord was like a devouring fire on the top of the mountain in the sight of the people of Israel." — Exodus 24:17 (ESV). A man walks into what looks like a consuming fire. He does not come back for forty days and forty nights.
Keil and Delitzsch observe that the six days of waiting before God's call on the seventh day mirrors the pattern of the creation week — six days of preparation and presence, and then a seventh-day encounter. Whether or not the parallel is fully intentional, the forty days Moses spends within the cloud are among the most consequential in the Old Testament. It is during this time that God gives him the detailed instructions for the tabernacle, the priesthood, the sacrificial system, and the Sabbath covenant sign — the entire blueprint of Exodus 25–31. The cloud that looks from below like devouring fire is, from within, an extended audience with God. Moses descends forty days later with more than he can carry: two tablets written by God's finger, a face that shines with reflected glory, and the complete pattern for the worship structure that will define Israel's life before God for centuries.
We keep coming back to what Moses walks into: fire. From the outside, it looks like death. From the inside, it is conversation. That gap between how God's presence looks from a distance and what it actually is up close runs through the whole Bible. The disciples in the storm at sea think Jesus is a ghost. Saul on the road to Damascus is thrown to the ground by what will turn out to be the risen Christ welcoming him. The holiness that terrifies from outside is, when you enter it with God's invitation, the place where you hear His voice most clearly.
