Numbers 20:9

5 Why have you led us up out of Egypt to bring us to this wretched place? It is not a place of grain, figs, vines, or pomegranates—and there is no water to drink!”

6 Then Moses and Aaron went from the presence of the assembly to the entrance to the Tent of Meeting. They fell facedown, and the glory of the LORD appeared to them.

7 And the LORD said to Moses,

8 “Take the staff and assemble the congregation. You and your brother Aaron are to speak to the rock while they watch, and it will pour out its water. You will bring out water from the rock and provide drink for the congregation and their livestock.”

9 So Moses took the staff from the LORD’s presence, just as he had been commanded.

10 Then 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?”

11 Then 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.

12 But 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.”

13 These were the waters of Meribah, where the Israelites quarreled with the LORD, and He showed His holiness among them.
