That he struck the rock instead of talking to it.

Yahweh spoke to Moses, saying, “Take the rod, and assemble the congregation, you, and Aaron your brother, and speak to the rock before their eyes, that it pour out its water. You shall bring water to them out of the rock; so you shall give the congregation and their livestock drink.” Moses took the rod from before Yahweh, as he commanded him. Moses and Aaron gathered the assembly together before the rock, and he said to them, “Hear now, you rebels! Shall we bring water out of this rock for you?” Moses lifted up his hand, and struck the rock with his rod twice, and water came out abundantly. The congregation and their livestock drank. Yahweh said to Moses and Aaron, “Because you didn’t believe in me, to sanctify me in the eyes of the children of Israel, therefore you shall not bring this assembly into the land which I have given them.”
Examining the tension
What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Genuinely disputed among scholars
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
Numbers 20:7-12 bars Moses (and Aaron) from the promised land because, commanded to *speak* to the rock at Meribah, Moses instead struck it twice, and YHWH judged: "Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land." Deuteronomy 3:26-27 (cf. 4:21) instead has Moses tell Israel, "The LORD was wroth with me *for your sakes*, and would not hear me" — attributing his exclusion to the people.
The apologetic harmonization is the both-and reading, advanced by Eugene Merrill (NAC *Deuteronomy*), Daniel Block (NIVAC *Deuteronomy*), and Gleason Archer: Moses was punished for his own Meribah failure, but that failure occurred in the context of the people's provocation (Num 20:2-5), so Deuteronomy's "for your sakes" means "because of the situation you put me in." This reading has genuine textual support. Deuteronomy itself does not deny Moses' personal fault: in the same book, Deuteronomy 32:51 has YHWH state that Moses and Aaron "trespassed against me among the children of Israel at the waters of Meribah-Kadesh... because ye sanctified me not." That is the Numbers charge restated within Deuteronomy. And the Hebrew of 3:26, *bigelalkem* ("on your account," "for your sakes"), can plausibly carry the broad sense "because of what you brought about." So a flat denial of any contradiction is too strong: Deuteronomy knows the Meribah charge.
Where the harmonization weakens is the rhetorical posture of Deuteronomy 3:23-27 in its own context. There Moses recounts pleading with YHWH to be allowed across the Jordan, and frames the refusal as YHWH being "wroth with me for your sakes." The whole movement deflects responsibility outward — Deuteronomic Moses presents himself as the long-suffering mediator bearing the consequences of the congregation's recurring rebellion, the book's central theological theme. That portrait sits in tension with the Priestly Numbers 20 Moses who himself fails at the decisive moment of testing. Source critics including Joel Baden and Thomas Dozeman read the two as distinct traditions: the Priestly account needs to explain why even Moses fell short, and supplies a specific covenant infraction at the rock; the Deuteronomic account, organized around communal disobedience, folds Moses' loss into the same pattern of the people's sin. Deuteronomy 32:51, which does name Moses' own trespass, belongs to a different (likely later) stratum than the Deuteronomic prose of chapter 3 — so the appeal to 32:51 to interpret 3:26 is itself a cross-source harmonization rather than a reading of a single voice.
A further complication is that Numbers 20 is itself unclear about what exactly Moses did wrong. "Because ye believed me not, to sanctify me" is vague. Was the sin striking instead of speaking? Saying "must *we* fetch you water" (20:10), arrogating the miracle? Displaying anger rather than faith? Jacob Milgrom (JPS *Numbers*) catalogues the rabbinic options and concludes the text does not specify, which makes the cross-textual comparison with Deuteronomy still harder to control.
Where the critical reading lands: moderate, partially harmonizable. The both-and reading is textually defensible because Deuteronomy 32:51 affirms Moses' transgression and *bigelalkem* is elastic enough to absorb it. But the source-critical evidence points to two traditions with divergent emphases — Priestly individual failure at the rock versus Deuteronomic communal failure — set side by side without the canon ever fully reconciling whose fault cost Moses the land.
