Deuteronomy 23:21
JPS-1917לַנׇּכְרִ֣י תַשִּׁ֔יךְ וּלְאָחִ֖יךָ לֹ֣א תַשִּׁ֑יךְ לְמַ֨עַן יְבָרֶכְךָ֜ יְהֹוָ֣ה אֱלֹהֶ֗יךָ בְּכֹל֙ מִשְׁלַ֣ח יָדֶ֔ךָ עַל־הָאָ֕רֶץ אֲשֶׁר־אַתָּ֥ה בָא־שָׁ֖מָּה לְרִשְׁתָּֽהּ׃ {ס}
Unto a foreigner thou mayest lend upon interest; but unto thy brother thou shalt not lend upon interest; that the LORD thy God may bless thee in all that thou puttest thy hand unto, in the land whither thou goest in to possess it.
Rashi Commentary
לנכרי תשיך UNTO AN ALIEN THOU MAYEST LEND UPON INTEREST (according to Rashi: TO AN ALIEN THOU MAYEST PAY INTEREST) — but not to thy brother. Such a prohibition which is not plainly stated but can only be drawn by inference from a positive command is itself regarded only as a positive command — so that one who pays interest to his brother transgresses two negative commands: לא תשיך in v. 20, ולאחיך לא תשיך in v. 21 and a positive command לנכרי תשיך — ולאחיך לא (cf. Sifrei Devarim 263:1; Bava Metzia 70b; also cf. Rashi on Deuteronomy 14:20).
