Numbers 20:10-12

10Moses and Aaron summoned the assembly in front of the rock, and Moses said to them, “Listen, you rebels! Must we bring water out of this rock for you?”

11Then Moses raised his hand and struck the rock twice with his staff, so that abundant water gushed out, and the community and their livestock drank.

12But the Lord said to Moses and Aaron, “Because you did not trust me to demonstrate my holiness in the sight of the Israelites, you will not bring this assembly into the land I have given them.”
