מֹ֧אזְנֵי צֶ֣דֶק אַבְנֵי־צֶ֗דֶק אֵ֥יפַת צֶ֛דֶק וְהִ֥ין צֶ֖דֶק יִהְיֶ֣ה לָכֶ֑ם אֲנִי֙ יְהוָ֣ה אֱלֹֽהֵיכֶ֔ם אֲשֶׁר־הוֹצֵ֥אתִי אֶתְכֶ֖ם מֵאֶ֥רֶץ מִצְרָֽיִם׃
Ayez des balances exactes, des poids exacts, une épha exacte, un men exact: Je suis l’Éternel votre Dieu, qui vous ai fait sortir du pays d’Égypte.
Mishnah Sheviit
One who repays his debts after the seventh year, the sages are pleased with him. One who borrows from a convert whose sons had converted with him, the debt need not be repaid to his sons, but if he returns it the sages are pleased with him. All movable property can be acquired [only] by the act of drawing, but whoever fulfills his word, the sages are well pleased with him.
