Numbers 20:10-12

10and Moses and Aaron gathered the assembly before the rock. And he said to them, “1Listen now, you rebels; shall we bring forth water for you out of this rock?”

11Then Moses lifted up his hand and struck the rock twice with his rod; and 2water came forth abundantly, and the congregation and their beasts drank.

12But the Lord said to Moses and Aaron, “3Because you have not believed Me, to treat Me as holy in the sight of the sons of Israel, therefore you shall not bring this assembly into the land which I have given them.”
