Números 20:12

12 But the Lord said to Moses and Aaron, "Because you did not trust in me enough to honor me as holy in the sight of the Israelites, you will not bring this community into the land I give them."

12 Then the Lord said to Moses and Aaron, Because you had not enough faith in me to keep my name holy before the children of Israel, you will not take this people into the land which I have given them.
