Numbers 20:10-12

10Then Moses and Aaron gathered the assembly in front of the rock, and Moses said to them, “Listen now, you rebels, must we bring you water out of this rock?” 11Then Moses raised his hand and struck the rock twice with his staff, so that a great amount of water gushed out, and the congregation and their livestock were able to drink.

12But the LORD said to Moses and Aaron, “Because you did not trust Me to show My holiness in the sight of the Israelites, you will not bring this assembly into the land that I have given them.”
