Numbers 20:11-13

Then Moses raised his hand [in anger] and with his rod he struck the rock twice [instead of speaking to the rock as the LORD had commanded]. And the water poured out abundantly, and the congregation and their livestock drank [fresh water]. But the LORD said to Moses and Aaron, “Because you have not believed (trusted) Me, to treat Me as holy in the sight of the sons of Israel, you therefore shall not bring this assembly into the land which I have given them.” [Ps 106:32, 33] These are the waters of Meribah (contention, strife), where the sons of Israel contended with the LORD, and He showed Himself holy among them.
