Numbers 20:7-10

⁷And the Lord spoke unto Moses, saying,

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

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

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