Pesachim, 13a: The Gaba'im of Tzedakah, who do not have poor people to whom to distribute, may exchange copper P'rutos ¹ on behalf of others but not on behalf of themselves, and the Gaba'im of soup-kitchens who do not have poor people to whom to distribute, may sell food to others but not to themselves - because the Torah writes "vi'Hiyisem Neki'im me'Hashem u'mi'Yisrael". ²

Shekalim, 3:2: The Kohen who takes money (for the Korbanos) from the room where the half-Shekalim are kept, is not allowed to enter wearing a double garment, shoes, sandals, ³ Tefilin or a Kame'a - all of which contain folds or compartments into which things can be placed - in case he becomes poor or eich, and people accuse him of having become poor as a punishment for stealing from Hekdesh or rich from the proceeds of Hekdesh money - because the Torah writes "Viheyisem Neki'im me'Hashem u'mi'Yisrael".

Yerushalmi Shekalim, 3:2 #1: It implies that, it is not sufficient to be innocent in the Eyes of Hashem, but that one needs to be innocent in the eyes of people too - and we learn this from the Torah, from Nevi'im and from Kesuvim. ⁴

Yerushalmi Shekalim, 3:2 #2: In Torah, in Nevi'im and in Kesuvom, we find that a person must fulfil his duty (by avoiding suspicion) with regard to people no less than with regard to Hashem: In Torah - "Vih'yisem Neki'im me'Hashem u'mi'Yisrael"; In Nevi'im - "Keil Elokim Hashem Hu Yode'a, ve'Yisrael Hu Yode'a" (Yehoshu'a, 22:22); In Kesuvim: "u'Metza Chein ve'Seichel Tov be'Einei Elokim ve'Adam" (Mishlei, 3:4). The best of these is "Viheyisem Neki'im me'Hashem u'mi'Yisrael". ⁵
