What Is Exodus 20? The Chapter Behind the Commandments

Exodus 20 is one of the most quoted chapters in the Bible and one of the least read to the end. Most people know its first seventeen verses — the Ten Commandments — and stop there. But the chapter has twenty-six verses, and the last nine tell you what happened when God finished speaking: a nation backing away in fear, Moses walking toward the darkness alone, and an unexpectedly gentle set of instructions about how ordinary people could come near.

The setting is Mount Sinai, three months after Israel left Egypt (Exodus 19:1). Chapter 19 is all preparation — boundaries around the mountain, washed clothes, a warning not to touch the slope, and then thunder, lightning, thick cloud, and a trumpet blast growing louder. Chapter 20 is what all of that was for. It is the only moment in the Bible where God speaks aloud, in words, to an entire people at once.

God spoke all these words, saying, “I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage.”

Exodus 20:1–2

Notice the first verb. God spoke. The Ten Commandments were heard before they were ever carved in stone, and they begin not with an order but with an introduction — a rescuer naming himself. Everything that follows is addressed to people who have already been brought out.

The ten commands themselves run from verse 3 to verse 17. This site has a full article on what each of the Ten Commandments means and another on the list in order, so here are only the things that are easy to miss in the chapter itself:

• They are addressed to “you” in the singular. Hebrew distinguishes between one person and a crowd, and God speaks to each listener individually. Nobody at Sinai could hear the commands as meant for somebody else.
• Eight of the ten are negative. “You shall not” marks a boundary, and a boundary leaves the whole field inside it free. The list says very little about what to do and a great deal about what not to destroy.
• The two positive commands are about time and family. Remember the Sabbath; honor your parents. Rest and household are the only things the list tells you to actively do.
• Only two commands come with reasons. The Sabbath, because God rested; honoring parents, so that your days may be long. The other eight are simply spoken, as if their reasons were obvious.
• The last one cannot be seen. Nine commands govern actions and words. The tenth, against coveting, governs desire — a law no court could ever enforce. There is a separate article on what “you shall not covet” means.

All the people perceived the thunderings, the lightnings, the sound of the trumpet, and the mountain smoking. When the people saw it, they trembled, and stayed at a distance. They said to Moses, “Speak with us yourself, and we will listen; but don't let God speak with us, lest we die.”

Exodus 20:18–19

This is the part of the chapter the posters leave out. The people do not respond to the Ten Commandments with a vow of obedience; they respond with terror. Hearing God directly is more than they can bear, and they ask for a go-between. From here on, that is how Israel will receive the law — through Moses, standing between the mountain and the camp.

Moses's reply is careful. “Don't be afraid,” he says, and then, in the same breath, “God has come to test you, and that his fear may be before you, that you won't sin” (v. 20). Both halves are true. God is not to be feared as an enemy; he is to be feared as God — and the memory of Sinai, the chapter suggests, is meant to keep the commandments from ever becoming casual. Then verse 21: the people stay at a distance, and Moses walks into the thick darkness where God is. It is one of the quietest and bravest sentences in Exodus.

What God says next, after the thunder, is surprising for how small it is. No grand temple, no priesthood yet — just instructions for an altar.

You shall make an altar of earth for me, and shall sacrifice on it your burnt offerings and your peace offerings, your sheep and your cattle. In every place where I record my name I will come to you and I will bless you. If you make me an altar of stone, you shall not build it of cut stones; for if you lift up your tool on it, you have polluted it.

Exodus 20:24–25

Three things stand out. First, the altar is made of earth or uncut stone — nothing shaped, nothing impressive, nothing a craftsman could take credit for. The people who have just been told not to make images are told, in effect, not to make their worship a monument to themselves either. Second, God promises to come to them — “in every place where I record my name I will come to you.” The God of the smoking mountain intends to be approachable. Third, there are to be no steps up to the altar (v. 26): the one who approaches should not be raised up, exposed, or on display. Worship in Exodus 20 ends with humility, not spectacle.

Read as a whole, the chapter has a shape. It opens with rescue, moves through the ten words, passes through fear, and ends with a way to come near. That is not a bad summary of the whole Bible.

The Ten Commandments appear a second time in Deuteronomy 5, when Moses repeats them forty years later to the children of the generation that stood at Sinai. The ten are the same, but the details shift in ways worth noticing. Deuteronomy says “observe” the Sabbath rather than “remember” it, and grounds the day not in creation but in the exodus: rest, because you were once slaves who never could. It also names the neighbor's wife before his house in the tenth commandment. The commands do not change; the second telling simply speaks to people who had not been there the first time. The list in order sets those differences side by side.

Two chapters, then, and one moment. Exodus 20 is the original — the voice from the mountain, the trembling crowd, the altar of earth. It is the hinge of the whole book: everything before it is a people being rescued, and everything after it is a rescued people learning to live free.

That is also why this site is called Exode 20. Exode is simply the French word for Exodus, and the name points at this chapter — the place where a God who has already brought people out tells them, in ten short sayings, what their freedom is for. If you have children, there is a version of the list in kid-sized words; if you have never read the whole chapter aloud, it takes about three minutes, and it is a different chapter when heard as one speech.

What is Exodus 20 about?

It records God speaking the Ten Commandments aloud to Israel at Mount Sinai (verses 1–17), the people's fearful response and Moses stepping in as mediator (verses 18–21), and instructions for a simple altar of earth or uncut stone (verses 22–26). It is the moment the rescued nation receives the terms of its covenant with God.

How many verses are in Exodus 20?

Twenty-six. The Ten Commandments occupy verses 3 to 17, with the introduction in verses 1 and 2. The remaining nine verses — the people's fear and the altar instructions — are the part most readers skip.

Who is speaking in Exodus 20?

God speaks directly in verses 1 to 17 and again in verses 22 to 26. The people speak once, in verse 19, asking Moses to stand between them and God. Moses answers in verse 20. It is the only chapter in which God addresses the whole nation in audible words.

Is Exodus 20 the same as Deuteronomy 5?

Both contain the Ten Commandments, and the commands are the same. Deuteronomy 5 is Moses repeating them to the next generation forty years later, with small differences in wording — a different reason for the Sabbath, “observe” instead of “remember,” and a different order within the tenth commandment.

What comes after Exodus 20?

Exodus 21 to 23, often called the Book of the Covenant — detailed laws that apply the ten to daily life: servants, injuries, property, honesty in court, care for the poor and the stranger. Then in Exodus 24 the covenant is sealed with a meal on the mountain, and Moses goes up to receive the stone tablets.
