Numbers 20:8-10

⁸Take the rod, you and Aaron, your brother, and make all the people come together, and before their eyes give orders to the rock to give out its water; and so make water come out of the rock for them, and give the people and their cattle drink.

⁹And Moses took the rod from before the Lord as he gave him orders.

¹⁰Then Moses and Aaron made the people come together in front of the rock, and he said to them, Give ear now, you people whose hearts are turned from the Lord; are we to get water for you out of the rock?
