Numbers 20:7-9

American Standard Version

⁷ And Jehovah spake 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. ⁹ And Moses took the rod from before Jehovah, as he commanded him.
