Numbers 20:7-10

⁷Yahweh spoke to Moses and said,

⁸“Take the staff and assemble the community, you, and Aaron your brother. Speak to the rock before their eyes, and command it to flow with water. You will produce water for them out of that rock, and you must give it to the community and their cattle to drink.”

⁹Moses took the staff from before Yahweh, as Yahweh had commanded him to do.

¹⁰Then Moses and Aaron gathered the assembly together before the rock. Moses said to them, “Listen now, you rebels. Must we bring water out of this rock for you?”
