Deuteronomy 15:7

כי יהיה בך אביון IF THERE BE AMONG YOU A NEEDY MAN — The most needy has preference (Sifrei Devarim 116:4); מאחד אחיך ONE OF THY BRETHREN — thy brother on thy fathers side has preference over thy brother on thy mother’s side (Sifrei Devarim 116:5); שעריך [WITHIN ANY OF] THY GATES — this implies that the poor of thine own city have preference over the poor of another city (Sifrei Devarim 116:6; cf. Rashi on Exodus 22:24). לא תאמץ THOU SHALT NOT MAKE [THY HEART] OBSTINATE — There are people who painfully deliberate whether they should give or not, therefore Scripture states, “thou shalt not make thy heart obstinate”; there again are people who stretch their hand forth (show readiness to give) but then close it, therefore it is written, “thou shalt not close thine hand” (Sifrei Devarim 116:10-11). מאחיך מאביון [NOR CLOSE THINE HAND] FROM THY NEEDY BROTHER — If you will not give him you will become in the end a brother of the needy (become as needy as himself) (cf. Sifrei Devarim 116:12).

כִּֽי־יִהְיֶה֩ בְךָ֨ אֶבְי֜וֹן מֵאַחַ֤ד אַחֶ֙יךָ֙ בְּאַחַ֣ד שְׁעָרֶ֔יךָ בְּאַ֨רְצְךָ֔ אֲשֶׁר־יְהֹוָ֥ה אֱלֹהֶ֖יךָ נֹתֵ֣ן לָ֑ךְ לֹ֧א תְאַמֵּ֣ץ אֶת־לְבָבְךָ֗ וְלֹ֤א תִקְפֹּץ֙ אֶת־יָ֣דְךָ֔ מֵאָחִ֖יךָ הָאֶבְיֽוֹן׃

If there be among you a poor man, one of thy brethren within any of thy gates in thy land which the Lord thy God gives thee, thou shalt not harden thy heart, nor shut thy hand from thy poor brother:
