It is not proper to act in a disrespectful manner even towards oneself. One should not do anything that does not match his own dignity, for the Torah cares about the dignity of people — as we see, for example, that the Torah exempts a scholar from returning lost articles if it is not becoming of his stature. Yet, when it comes to studying Torah, one should humble himself and speak Torah with all people, whether small or great. Similarly, when it comes to doing any mitzvah, one should do it himself, and that is the person’s honor. We thus find that the greatest among the Jewish people would personally engage in Shabbos preparations, and that king David danced with all his might before the Ark of the Covenant. And in Tehillim it is written: From all my teachers I grew wise (Tehillim 119:99). Our Sages, as well, said: “Who is wise? He who learns from every man.” This is the correct path which brings glory to the person and brings respect from others.
