Numbers 20:6–8

6 Then 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. 7 The Lord spoke to Moses, 8 “Take the staffm and assemble the community. You and your brother Aaron are to speak to the rockn 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.”
