Numbers 20:8-11

8“Take 1the 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.”

9So Moses took the rod 2from before the Lord, just as He had commanded him; 10and Moses and Aaron gathered the assembly before the rock. And he said to them, “3Listen now, you rebels; shall we bring forth water for you out of this rock?” 11Then Moses lifted up his hand and struck the rock twice with his rod; and 4water came forth abundantly, and the congregation and their beasts drank.
