Psalms 106:32

They angered him also at the waters of strife - Numbers 20:3. They complained of the lack of water. They wished that they had died as others had done. They murmured against God as if he could not supply their needs. They showed an unbelieving and rebellious spirit - provoking God, and tempting Moses to in act of great impatience by their conduct. In Numbers 20:13, this is, “the waters of Meribah;” - margin, “strife.” This is the meaning of the Hebrew word. The place took its name from the fact that the people there strove against the Lord and against Moses.

So that it went ill with Moses for their sakes - Evil came upon him. He was betrayed into impatience, and was tempted to use words which offended God, and prevented his being permitted to lead the people into the promised land. Numbers 20:12.
