Numbers 20:8; Numbers 20:9; Numbers 20:11

8 "Take the rod; and you and your brother Aaron assemble the congregation and speak to the rock before their eyes, that it may yield its water. You shall thus bring forth water for them out of the rock and let the congregation and their beasts drink."

9 So Moses took the rod from before the LORD , just as He had commanded him;

11 Then Moses lifted up his hand and struck the rock twice with his rod; and water came forth abundantly, and the congregation and their beasts drank.
