Numbers 20:12

8 “Take the staff and assemble the congregation. You and your brother Aaron are to speak to the rock while they watch, and it will pour out its water. You will bring out water from the rock and provide drink for the congregation and their livestock.”

9 So Moses took the staff from the LORD’s presence, just as he had been commanded.

10 Then Moses and Aaron gathered the assembly in front of the rock, and Moses said to them, “Listen now, you rebels, must we bring you water out of this rock?”

11 Then Moses raised his hand and struck the rock twice with his staff, so that a great amount of water gushed out, and the congregation and their livestock were able to drink.

12 But the LORD said to Moses and Aaron, “Because you did not trust Me to show My holiness in the sight of the Israelites, you will not bring this assembly into the land that I have given them.”

13 These were the waters of Meribah, where the Israelites quarreled with the LORD, and He showed His holiness among them.

14 From Kadesh, Moses sent messengers to tell the king of Edom, “This is what your brother Israel says: You know all the hardship that has befallen us,

15 how our fathers went down to Egypt, where we lived many years. The Egyptians mistreated us and our fathers,

16 and when we cried out to the LORD, He heard our voice, sent an angel, and brought us out of Egypt. Now look, we are in Kadesh, a city on the edge of your territory.
