Numbers 20:11-12, 24

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]

“Aaron will be gathered to his people [in death]; for he shall not enter the land which I have given to the children of Israel, because you [both] rebelled against My command at the waters of Meribah. [Num 20:7-12]
