Moses' disobedience cost him his leadership position

Numbers 20:7-8, 11-12

The LORD spoke to Moses, saying, “Take the rod, and assemble the congregation, you, and Aaron your brother, and speak to the rock before their eyes, that it pour out its water. You shall bring water to them out of the rock; so you shall give the congregation and their livestock drink.” Moses lifted up his hand, and struck the rock with his rod twice, and water came out abundantly. The congregation and their livestock drank. The LORD said to Moses and Aaron, “Because you didn’t believe in me, to sanctify me in the eyes of the children of Israel, therefore you shall not bring this assembly into the land which I have given them.”
