Numbers 12:11 New International Version (NIV)
11 and he said to Moses, “Please, my lord, I ask you not to hold against us the sin we have so foolishly committed.
Aaron asked that he and Miriam not be punished for their sin. It can be easy to look back at mistakes and recognize the foolishness. It is even more difficult to recognize foolish plans when you are right in the middle of them. How do you keep from making foolish mistakes? Eliminate wrong thoughts and motives. Go to wise and steadfast friends or mentors for advice when you question your thoughts or motives. They can help shed light and keep you from making hurtful mistakes.
