Numbers 20:6-8

⁶Then Moses and Aaron went away from the people to the door of the Tent of meeting; and, falling on their faces there, they saw the glory of the Lord.

⁷And the Lord said to Moses,

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.
