סימן כט סעיף כ

צָרִיךְ הָאָדָם לִזָּהֵר, שֶׁלֹּא לַעֲשׂוֹת אֵיזֶה דָּבָר, שֶׁיְכוֹלִין לַחְשֹׁד אוֹתוֹ שֶׁעָשָׂה דְּבַר עֲבֵרָה, (אַף עַל פִּי שֶׁאֵינוֹ עוֹשֶׂה) כִּדְמָצִינוּ שֶׁהַכֹּהֵן הַתּוֹרֵם אֶת הַלִּשְׁכָּה לֹא הָיָה נִכְנַס בְּבֶגֶד הֶעָשׂוּי. בְּעִנְיָן שֶׁיְכוֹלִין לְהַטְמִין בּוֹ אֵיזֶה דָּבָר, לְפִי שֶׁצָּרִיךְ הָאָדָם לָצֵאת יְדֵי הַבְּרִיּוֹת כְּדֶרֶךְ שֶׁהוּא צָרִיךְ לָצֵאת יְדֵי הַמָּקוֹם בָּרוּךְ הוּא שֶׁנֶּאֱמַר, וִהְיִיתֶם נְקִיִּים מֵה' וּמִיִשְֹרָאֵל. וְאוֹמֵר וּמְצָא חֵן וְשֵׂכֶל טוֹב בְּעֵינֵי אֱלֹהִים וְאָדָם.

A person should be careful not to do anything which might cause [people] to suspect that he committed a sin, (even though he is not [actually] committing a sin), as we find⁶³Shekalim 3:2. that the kohein who removed the coins from the chamber⁶⁴The coins of machatzis hashekel, the half shekel which every Jew is obligated to give once each year, were deposited in large collection boxes. These boxes were placed in a chamber in the Bais Hamikdash, designated for this purpose. Three times annually a kohein would enter this chamber to withdraw coins with which sacrifices and other necessities were bought.
The garment he wore had no pockets, so as not to arouse suspicion that he had taken some coins for himself. (Rambam, Hilchos Shekalim 2:4, 5, 10) did not enter [the chamber] in a garment that was fashioned in a way that something could be hidden in it, for a person must answer for his actions to his fellow man as he must answer to the Almighty, blessed is He, as it is said: "You will be innocent before God and Israel"⁶⁵Numbers 32:22. And it is also said: "And find favor and good understanding in the eyes of God and man."⁶⁶Proverbs 3:4.

תנא דבי אליהו כל השונה הלכות בכל יום מובטח לו שהוא בן העולם הבא שנאמר הליכות עולם לו אל תקרי הליכות אלא הלכות (נדה ע"ג.)
