Numbers 20:9-11

Amplified Bible

⁹ So Moses took the rod from before the Lord, just as He had commanded him; ¹⁰ and Moses and Aaron gathered the assembly before the rock. Moses said to them, “Listen now, you rebels; must we bring you water out of this rock?” ¹¹ Then Moses raised his hand [in anger] and with his rod he struck the rock twice [instead of speaking to the rock as the Lord had commanded]. And the water poured out abundantly, and the congregation and their livestock drank [fresh water].
