Numbers 20:6-9

6Then Moses and Aaron went from the presence of the assembly to the doorway of the tent of meeting. They fell facedown, and the glory of the Lord appeared to them.

7The Lord spoke to Moses,

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

9So Moses took the staff from the Lord’s presence just as he had commanded him.
