Korach questioned the authority of Moshe Rabenu

When Korach questioned the authority of Moshe Rabenu he thought that he knew more then Moshe. We learn from this that if we have a question about something we are learning it is important to act from humility and admit that we do not understand, rather then thinking that we know better.
