Numbers 20:6-12

⁶And Moses and Aaron went from the presence of the assembly unto the door of the tent of meeting, and fell upon their faces; and the glory of the LORD appeared unto them.

⁷And the LORD spoke unto Moses, saying:

⁸'Take the rod, and assemble the congregation, thou, and Aaron thy brother, and speak ye unto the rock before their eyes, that it give forth its water; and thou shalt bring forth to them water out of the rock; so thou shalt give the congregation and their cattle drink.'

⁹And Moses took the rod from before the LORD, as He commanded him.

¹⁰And Moses and Aaron gathered the assembly together before the rock, and he said unto them: 'Hear now, ye rebels; are we to 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 the LORD 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.'
