5וְכֵן בְּפֶרֶט שֶׁנִּפְרַט מִן הָעֲנָבִים בִּשְׁעַת הַבְּצִירָה וְכֵן בְּעוֹלֵלוֹת שֶׁנֶּאֱמַר (ויקרא יט י) "וְכַרְמְךָ לֹא תְעוֹלֵל וּפֶרֶט כַּרְמְךָ לֹא תְלַקֵּט לֶעָנִי וְלַגֵּר תַּעֲזֹב אֹתָם". וְכֵן הַמְעַמֵּר וְשָׁכַח אֲלֻמָּה אַחַת בַּשָּׂדֶה הֲרֵי זֶה לֹא יִקָּחֶנָּה שֶׁנֶּאֱמַר (דברים כד יט) "וְשָׁכַחְתָּ עֹמֶר בַּשָּׂדֶה לֹא תָשׁוּב לְקַחְתּוֹ". עָבַר וּלְקָטוֹ אֲפִלּוּ טְחָנוֹ וַאֲפָאוֹ הֲרֵי זֶה נוֹתְנוֹ לָעֲנִיִּים שֶׁנֶּאֱמַר (דברים כד יט) "לַגֵּר לַיָּתוֹם וְלָאַלְמָנָה יִהְיֶה" זוֹ מִצְוַת עֲשֵׂה הָא לָמַדְתָּ שֶׁכֻּלָּן מִצְוֹת לֹא תַּעֲשֶׂה הַנִּתָּק לַעֲשֵׂה הֵן וְאִם לֹא קִיֵּם עֲשֵׂה שֶׁבָּהֶן לוֹקֶה:
Similar [laws apply to] individual grapes that fall during the grape harvest and to underdeveloped grape clusters, as it is stated [ibid. 19:10]: "Do not harvest underdeveloped grape clusters from your vineyard, nor gather individual grapes that fall in your vineyard. Leave it for the poor and the stranger." Similarly, if a person is binding sheaves of wheat into bundles and forgets one bundle, he may not go back and take it, as [Deuteronomy 24:19] states: "If you forget a sheave in the field, do not return to take it." If he transgressed and gathered it - even if he ground it [into flour] and baked [it], he must give it to the poor, as it states [ibid.]: "They shall be for the stranger, the orphan, and the widow." This is a positive commandment. Thus you have learned that they all are prohibitions that can be corrected by positive commandments. If one [transgresses and] does not fulfill the positive commandment involved, he is worthy of lashes.
