Ten Commandments Compared: Exodus 20 vs. Deuteronomy 5

The Torah gives the Decalogue twice in major form: first in Exodus 20 at Sinai, then in Deuteronomy 5 as Moses addresses the generation preparing to enter Canaan. The two versions substantially overlap—but they are not word-for-word duplicates.

The same covenant core

Both versions begin from deliverance: the God giving these commands is the God who brought Israel out of Egypt, out of slavery. Both regulate loyalty to God, images, the divine name, Sabbath, parents, murder, adultery, theft, false witness and coveting.

This shared structure is why Jewish and Christian traditions treat the passages as two presentations of the same Decalogue rather than two unrelated moral codes.

The biggest difference: why keep Sabbath?

Exodus 20 grounds Sabbath in creation: six days of divine work followed by the seventh-day rest. Deuteronomy 5 grounds Sabbath in Israel’s slavery and liberation: Israel must remember having been enslaved in Egypt and therefore must allow servants and dependents to rest.

Those rationales are different. Canonically, they place Sabbath inside two foundational memories—creation and liberation.

“Remember” and “observe”

Exodus tells Israel to “remember” the Sabbath day; Deuteronomy tells Israel to “observe” or “keep” it. Later Jewish interpretation often treats the paired language as complementary rather than competitive.

Who gets rest?

Both passages extend Sabbath beyond the household head. Deuteronomy’s wording especially emphasizes that male and female servants should rest as the Israelite rests. That social dimension keeps Sabbath from becoming a private spiritual luxury for people powerful enough to take time off.

Coveting is phrased differently

The order and wording of the final prohibition differ. Deuteronomy distinguishes coveting a neighbor’s wife and desiring the neighbor’s house or property with wording that is not identical to Exodus.

Does difference mean contradiction?

Not automatically. “Contradiction” is a conclusion that must be argued, not a synonym for “different wording.” The more immediate observation is that Deuteronomy presents Moses restating covenant instruction for a new moment and gives explanatory emphases suited to that address.

Historical-critical scholarship asks additional questions about literary development and the relationship between legal collections. Those are legitimate scholarly questions, but they should be labeled as historical analysis rather than smuggled into the plain-text layer.

Why this matters for the authority series

Readers often imagine “the Ten Commandments” as one frozen plaque. The Torah is more interesting. It preserves a stable moral-covenantal core while allowing the remembered rationale to deepen: creation tells you that rest belongs to the order of life; Exodus tells you that liberated people must not rebuild slavery for others.
