NUMBERS 20:7-10

⁷And the LORD spake unto Moses, saying,

⁸Take 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; shall we bring you forth water out of this rock?
