Numbers 20:7-12
7 The Lord said to Moses, 8 ‘Get the stick from in front of the Covenant Box. Take your brother Aaron with you and go to the whole group of the Israelites. Then speak to that rock that you can all see. Water will pour out from it. You will give water to the people and their animals for them to drink.’
9 So Moses did what the Lord commanded him to do. He took the stick from its place in the tabernacle. 10 Then Moses and Aaron brought all the people to meet together in front of the rock. Moses said to them, ‘Listen now, you people who refuse to obey God. It seems that we must bring water out of this rock for you!’ 11 Moses lifted up his arm. He hit the rock twice with his stick. Water poured out from the rock. The people and their animals drank the water.
12 The Lord said to Moses and Aaron, ‘You did not trust me enough to show the Israelites that I am holy. So you will not lead them into the land that I have promised to give to them.’
