Deuteronomy 15:1

מִקְצֵה שָׁלֹשׁ שָׁנִים תּוֹצִיא אֶת־כָּל־מַעְשַׂר תְּבוּאָתְךָ בַּשָּׁנָה הַהִוא וְהִנַּחְתָּ בִּשְׁעָרֶֽיךָ

At the end of every three years, even in the same year, thou shalt bring forth all the tithe of thine increase, and shall lay it up within thy gates.

וּבָא הַלֵּוִי כִּי אֵֽין־לוֹ חֵלֶק וְנַחֲלָה עִמָּךְ וְהַגֵּר וְהַיָּתוֹם וְהָֽאַלְמָנָה אֲשֶׁר בִּשְׁעָרֶיךָ וְאָכְלוּ וְשָׂבֵעוּ לְמַעַן יְבָרֶכְךָ יְהוָה אֱלֹהֶיךָ בְּכָל־מַעֲשֵׂה יָדְךָ אֲשֶׁר תַּעֲשֶֽׂה

And the Levite, because he hath no portion nor inheritance with thee, and the stranger, and the fatherless, and the widow, that are within thy gates, shall come, and shall eat and be satisfied; that the LORD thy God may bless thee in all the work of thy hand which thou doest.

וְזֶה דְּבַר הַשְּׁמִטָּה שָׁמוֹט כָּל־בַּעַל מַשֵּׁה יָדוֹ אֲשֶׁר יַשֶּׁה בְּרֵעֵהוּ לֹֽא־יִגֹּשׂ אֶת־רֵעֵהוּ וְאֶת־אָחִיו כִּֽי־קָרָא שְׁמִטָּה לַֽיהוָֽה

And this is the manner of the release: every creditor shall release that which he hath lent unto his neighbour; he shall not exact it of his neighbour and his brother; because the LORD’S release hath been proclaimed.

אֶת־הַנָּכְרִי תִּגֹּשׂ וַאֲשֶׁר יִהְיֶה לְךָ אֶת־אָחִיךָ תַּשְׁמֵט יָדֶֽךָ

Of a foreigner thou mayest exact it; but whatsoever of thine is with thy brother thy hand shall release.
