The Ramban's Letter, Part Three

Consider everyone as greater than yourself. If he is wise or rich, you should give him respect. If he is poor and you are richer--or wiser--than he, consider yourself to be more guilty than he, and that he is more worthy than you, since when he sins it is through error, while yours is deliberate and you should know better!

~ from The Ramban's Letter to His Son (written by Iggeret HaRamban to his elder son, Nachman, with the instruction to read it weekly)

Honor one another above yourselves.

~ Romans 12:10
