Numbers 20:6-8

New Revised Standard Version, Anglicised

⁶ Then Moses and Aaron went away from the assembly to the entrance of the tent of meeting; they fell on their faces, and the glory of the Lord appeared to them. ⁷ The Lord spoke to Moses, saying: ⁸ Take the staff, and assemble the congregation, you and your brother Aaron, and command the rock before their eyes to yield its water. Thus you shall bring water out of the rock for them; thus you shall provide drink for the congregation and their livestock.
