אַל־תֹּ֘אמַ֤ר לרעיך [לְרֵֽעֲךָ֨ ׀] לֵ֣ךְ וָ֭שׁוּב וּמָחָ֥ר אֶתֵּ֗ן וְיֵ֣שׁ אִתָּֽךְ׃
Huwag mong sabihin sa iyong kapwa, “Umalis ka muna at bumalik ka, at bukas ay magbibigay ako,” gayong mayroon ka naman nito.
Avot DeRabbi Natan
How so? This teaches that just as a person sees his own money, so should he see his friend’s money. And just as a person does not want people to speak ([badly]) about his finances, so should he not want people to speak (badly) about his friend’s finances.
[Another interpretation of Let your friend’s money be as precious to you as your own:] How so? When a student enters your house (and says: Teach me), if you are able to teach him, teach him; if not, release him immediately, and do not take his money, as it says (Proverbs 3:28), “Do not say, Go, and come back tomorrow, and I will give it to you, when you have it on you.”
