Numbers 20:7-10

⁷And Jehovah spoke to Moses, saying,

⁸Take the staff, and gather the assembly together, thou, and Aaron thy brother, and speak ye unto the rock before their eyes, and it shall give its water; and thou shalt bring forth to them water out of the rock, and shalt give the assembly and their beasts drink.

⁹And Moses took the staff from before Jehovah, as he had commanded him.

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?
