על נפש מת לא יבא. לא יחלל עסקי קדושתו להתעסק בכבוד מתים כמו הענין בכהן גדול וכאמרם ז"ל המבלי אין קברים בטבריא שלחתיך בנציבין (במרדכי דמועד קטן בדיני אבילות הביא המאמר הזה בשם הירושלמי): על נפש מת לא יבא; he must not desecrate his sacred activities by honouring the dead and thereby downgrading his spiritual concerns. In this respect he is much like the High Priest. Our sages report that a father who had sent his son to study Torah in an advanced academy in Tiberias heard that his son was engaged in doing charitable deeds there. When the father heard about it he sent the following message to his son: “are there no opportunities to perform such charitable deeds in our town that I had to send you to Tiberias to do this?” (Jerusalem Talmud Chagigah 1,7) The point is that there are other people who can perform the charitable deed of burying the dead so that the services of the Nazirite are not required.
