Numbers 20:10-12

10And Moses and Aaron gathered the assembly together before the rock, and he said unto them, Hear now, ye rebels; shall we bring you forth water out of this rock? 11And Moses lifted up his hand, and smote the rock with his rod twice: and water came forth abundantly, and the congregation drank, and their cattle. 12And Jehovah said unto Moses and Aaron, Because ye believed not in me, to sanctify me in the eyes of the children of Israel, therefore ye shall not bring this assembly into the land which I have given them.
