Moses struck the ROCK, twice.Exo 17:4 And Moses cried unto the LORD, saying, What shall I do unto this people? they be almost ready to stone me. Exo 17:5 And the LORD said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go. Exo 17:6 Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel. Num 20:9 And Moses took the rod from before the LORD, as he commanded him. Num 20:10 And Moses and Aaron gathered the congregation together before the rock, and he said unto them, Hear now, ye rebels; must we fetch you water out of this rock? Num 20:11 And Moses lifted up his hand, and with his rod he smote the rock twice: and the water came out abundantly, and the congregation drank, and their beasts also.
