Deuteronomy – Ki Tiftach et Yadekha
Deuteronomy 15:7-11
The Torah commands: 'You shall surely open your hand to your poor and needy brother.' It forbids hardening one's heart or closing one's hand, and emphasizes giving generously according to the poor person's need — 'sufficient for whatever he lacks.'
כִּֽי־יִהְיֶה֩ בְךָ֨ אֶבְי֜וֹן מֵאַחַ֤ד אַחֶ֙יךָ֙ בְּאַחַ֣ד שְׁעָרֶ֔יךָ בְּאַ֨רְצְךָ֔ אֲשֶׁר־יְהֹוָ֥ה אֱלֹהֶ֖יךָ נֹתֵ֣ן לָ֑ךְ לֹ֧א תְאַמֵּ֣ץ אֶת־לְבָבְךָ֗ וְלֹ֤א תִקְפֹּץ֙ אֶת־יָ֣דְךָ֔ מֵאָחִ֖יךָ הָאֶבְיֽוֹן׃ כִּֽי־פָתֹ֧חַ תִּפְתַּ֛ח אֶת־יָדְךָ֖ ל֑וֹ וְהַעֲבֵט֙ תַּעֲבִיטֶ֔נּוּ דֵּ֚י מַחְסֹר֔וֹ אֲשֶׁ֥ר יֶחְסַ֖ר לֽוֹ׃ נָת֤וֹן תִּתֵּן֙ ל֔וֹ וְלֹא־יֵרַ֥ע לְבָבְךָ֖ בְּתִתְּךָ֣ ל֑וֹ כִּ֞י בִּגְלַ֣ל ׀ הַדָּבָ֣ר הַזֶּ֗ה יְבָרֶכְךָ֙ יְהֹוָ֣ה אֱלֹהֶ֔יךָ בְּכׇֽל־מַעֲשֶׂ֔ךָ וּבְכֹ֖ל מִשְׁלַ֥ח יָדֶֽךָ׃ כִּ֛י לֹא־יֶחְדַּ֥ל אֶבְי֖וֹן מִקֶּ֣רֶב הָאָ֑רֶץ עַל־כֵּ֞ן אָנֹכִ֤י מְצַוְּךָ֙ לֵאמֹ֔ר פָּ֠תֹ֠חַ תִּפְתַּ֨ח אֶת־יָדְךָ֜ לְאָחִ֧יךָ לַעֲנִיֶּ֛ךָ וּלְאֶבְיֹנְךָ֖ בְּאַרְצֶֽךָ׃ {ס}
If, however, there is a needy person among you, one of your kindred in any of your settlements in the land that the ETERNAL your God is giving you, do not harden your heart and shut your hand against your needy kindred. Rather, you must open your hand and lend whatever is sufficient to meet the need. Give readily and have no regrets when you do so, for in return the ETERNAL your God will bless you in all your efforts and in all your undertakings. For there will never cease to be needy ones in your land, which is why I command you: open your hand to the poor and needy kindred in your land.
Why it matters — The foundational biblical source for the obligation of tzedakah, establishing both the positive commandment to give and the prohibition against withholding.
