Numbers 20:7-10

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?'
