Numbers 20:7-11

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.
9 So Moses took the staff from before the Lord, as he had commanded him.
10 Moses and Aaron gathered the assembly together before the rock, and he said to them, "Listen, you rebels, shall we bring water for you out of this rock?"
11 Then Moses lifted up his hand and struck the rock twice with his staff; water came out abundantly, and the congregation and their livestock drank.
