Numbers 20:10-12

10And Moses and Aaron gathered the congregation together before the rock, and he said to them, Hear now, ye rebels: shall we bring forth to you water out of this rock?

11And Moses lifted up his hand, and with his staff smote the rock twice, and much water came out, and the assembly drank, and their beasts.

12And Jehovah said to Moses and to Aaron, Because ye believed me not, to hallow me before the eyes of the children of Israel, therefore ye shall not bring this congregation into the land that I have given them.
