Musar su Ecclesiaste 8:5

The רמז, hint, contained in the Torah's description of the four categories of שומרים, trustees, i.e. the שומר חנם, שומר שכר, שוכר, שואל, is to the parallel, opposite source, i.e the source of sanctity, קדושה. It is reminiscent of the statement that שומר מצוה לא ידע דבר רע (Kohelet 8,5), that he who "keeps" the commandments will know of no evil. These four categories are analogous to the letters in the four lettered name of G–d. Since the letter ה in that name occurs twice, the הלכות, religious rulings, in the case of the four trustees are in reality only three (The paid trustee and the person who pays for renting a utensil are treated similarly in the event they are charged with negligence).

From the deeds of the pious man mentioned above one learns the importance of rising at midnight or before dawn to mourn over the destruction of the Holy Temple and the slaughter of the righteous. It is immaterial whether a person does a little more or a little less, as long as his intentions are for the sake of Heaven (Berachos 5b). But let him not do this in order to receive acclaim, for then not only does he receive no reward, but he will even be punished. If his intentions are for the sake of Heaven, however, it states concerning him, “One who keeps a commandment will experience no misfortune” (Koheles 8:5). Moreover he will merit witnessing the rebuilding of Tziyon and Yerushalayim, Amein. — Based on the words of my teacher and mentor Rabbi Yosef, z”l.
