Numbers 20:6-12

Then Moses and Aaron went from the presence of the assembly to the entrance of the tent of meeting and fell on their faces. And the glory of the LORD appeared to them, and the LORD spoke to Moses, saying, “Take the staff, and assemble the congregation, you and Aaron your brother, and tell the rock before their eyes to yield its water. So you shall bring water out of the rock for them and give drink to the congregation and their cattle.” And Moses took the staff from before the LORD, as he commanded him. Then Moses and Aaron gathered the assembly together before the rock, and he said to them, “Hear now, you rebels: shall we bring water for you out of this rock?” And Moses lifted up his hand and struck the rock with his staff twice, and water came out abundantly, and the congregation drank, and their livestock. And the LORD said to Moses and Aaron, “Because you did not believe in me, to uphold me as holy in the eyes of the people of Israel, therefore you shall not bring this assembly into the land that I have given them.”
