Numbers 20:8-12

“Take the staff, and you and your brother Aaron gather the assembly together. Speak to that rock before their eyes and it will pour out its water. You will bring water out of the rock for the community so they and their livestock can drink.” So Moses took the staff from the LORD’s presence, just as he commanded him. He and Aaron gathered the assembly together in front of the rock and Moses said to them, “Listen, you rebels, must we bring you water out of this rock?” Then Moses raised his arm and struck the rock twice with his staff. Water gushed out, and the community and their livestock drank. But the LORD said to Moses and Aaron, “Because you did not trust in me enough to honor me as holy in the sight of the Israelites, you will not bring this community into the land I give them.”
