Devarim: self-esteem

When the Jewish people are told that they will be traveling through the territory of Eisav they are instructed to buy food and water from the locals, as Se'ir is Eisav's land and not to be conquered. Moshe then reminds the people that every one of their needs has been taken care of by G-d throughout their journey of forty years in the desert. Rashi explains that this does not mean that the people have everything and really do not need to do business with the local tribes -- had that been the intent the Torah should have said "You have all that you need." Instead, the Torah says "You are not lacking," meaning don't appear needy and wanting. To appear as beggars after G-d has provided for your every want and need shows a lack of appreciation.

Rashi reminds us of the importance of self-esteem. G-d has helped each of us in some way or another; one small way we can show our appreciation is by acknowledging that we are worth receiving his assistance.
