Numbers 20:6-9

6Moses and Aaron went away from the people to the door of the Tent of Meeting. They threw themselves down with their faces towards the ground. The glory of the Lord appeared to them.

7The Lord said to Moses,

8‘Get the stick. Take your brother Aaron with you and go to the whole group of the Israelites. Then speak to that rock that you can all see. Water will pour out from it. Then the people and their animals can drink it.’

9So Moses did what the Lord had told him. He took the stick from its place in the Lord's Tent of Meeting.
