The covenant and revelation at Mount Sinai make Israel’s departure from Egypt the foundation of a binding relationship with the LORD. At the mountain, the people hear the covenant’s terms, receive commandments governing worship and communal life, and affirm their willingness to obey; the agreement is then ratified through sacrifice and blood. The scene joins divine authority to collective obligation, setting Sinai’s revelation within a continuing covenantal history that is recalled again in later instruction.

Revelation and the Covenant Terms

The encounter begins in the third month after the Israelites leave Egypt, when they camp in the wilderness before Mount Sinai. The LORD recalls their deliverance and offers a distinctive communal status on condition that they heed His voice and keep His covenant: they are to be His treasured people, a kingdom of priests, and a holy nation. Moses conveys this offer to the elders, and the people answer together that they will do what the LORD has spoken. The covenant thus binds a remembered act of rescue to a present commitment and a future identity.

The Mountain, Its Boundaries, and the Commandments

Before the encounter, Moses is instructed to consecrate the people and have them wash their garments. A boundary is set around the mountain: neither the people nor the priests may cross it to approach the LORD without permission. On the third day, thunder, lightning, a thick cloud, and a loud horn accompany the LORD’s descent in fire; the mountain smokes and quakes. The people tremble, and Moses brings them from the camp to the foot of the mountain. The repeated warnings against crossing its limits make access to the revelation carefully ordered: the people remain below, while Moses is summoned upward, with Aaron permitted to accompany him under specified terms.

From the mountain, God gives the commandments, beginning with the claim that the LORD brought Israel out of Egypt, the house of bondage. The people are forbidden to worship other gods or make images for worship, and are warned against taking the LORD’s name in vain. The Sabbath is to be kept holy, with rest extending beyond the household head to children, servants, resident strangers, and cattle; the commandment is grounded in the LORD’s rest after creating heaven and earth. The remaining prohibitions address dishonoring parents, murder, adultery, theft, false testimony, and coveting a neighbor’s household and possessions. Together, these terms connect exclusive worship with family and community conduct.

Ratification and Continuing Memory

After the commandments, the people recoil from the thunder, lightning, horn, and smoking mountain, asking Moses to speak to them rather than have God address them directly. Moses tells them not to fear, explaining that the encounter tests them and is meant to keep them from sin; while they stand at a distance, he approaches the thick darkness where God is. The LORD then gives further instructions: Israel is not to make silver or gold gods, and worship is to be marked by an altar of earth or unhewn stone, without steps leading up to it.

The covenant is formally ratified when Moses recounts the LORD’s words and ordinances, writes them down, and builds an altar beneath the mountain alongside twelve pillars representing Israel’s twelve tribes. Young Israelites offer burnt offerings and oxen as peace offerings. Moses places half the blood in basins and casts half against the altar; after reading the Book of the Covenant aloud, he sprinkles the remaining blood on the people and identifies it as the blood of the covenant. The public assent and the ritual together bind the people to the written terms.

Moses, Aaron, Nadab, Abihu, and seventy elders then ascend and behold the God of Israel; they are not harmed, and they eat and drink. Moses is subsequently summoned higher to receive stone tablets, the law, and commandments for teaching. Joshua accompanies him partway, while the elders remain with Aaron and Hur to handle disputes. A cloud covers Mount Sinai for six days; on the seventh, the LORD calls Moses, whose stay in the mountain lasts forty days and forty nights. The revelation therefore extends beyond the initial commandments into instruction meant to be transmitted and preserved.

Later accounts recall Sinai as a covenant made not only with an earlier generation but with the Israelites addressed in the present: Moses says the LORD spoke with them face to face from the fire, while he stood between the LORD and the people to convey the words because they feared the fire. This retelling restates the commandments and emphasizes Sabbath rest for servants and resident strangers as well as the household, grounding it in Israel’s memory of bondage and deliverance. The covenant’s force is also framed through consequences: obedience is associated with blessing, while turning to other gods brings covenant curses and exile. In the account of the covenant at Moab, the written law is placed beside the Ark of the Covenant, publicly read at the end of every seven years, and joined to a song and heaven and earth as witnesses. Sinai thus becomes both a foundational revelation and a continuing standard by which Israel’s later conduct is remembered and judged.
