Numbers 20:10-13 - Moses Strikes The Rock
10 And Moses and Aaron assembled the congregation before the rock, and he said to them, Hear now, ye rebels; must we fetch you water out of this rock? 11 And Moses lifted 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.
12 And the LORD spoke to Moses and Aaron, Because ye believed me not, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this congregation into the land which I have given them. 13 This is the water of Meribah; because the children of Israel strove with the LORD, and he was sanctified in them.
