11סְפֵק עָרְלָה וְכִלְאֵי הַכֶּרֶם בְּאֶרֶץ יִשְׂרָאֵל אָסוּר. בְּסוּרְיָא וְהִיא אֲרָצוֹת שֶׁכָּבַשׁ דָּוִד מֻתָּר. כֵּיצַד. הָיָה כֶּרֶם וְעָרְלָה וַעֲנָבִים נִמְכָּרוֹת חוּצָה לוֹ. הָיָה יָרָק זָרוּעַ בְּתוֹכוֹ וְיָרָק נִמְכָּר חוּצָה לוֹ. שֶׁמָּא מִמֶּנּוּ הוּא זֶה שֶׁמָּא מֵאַחֵר. בְּסוּרְיָא מֻתָּר. וּבְחוּץ לָאָרֶץ אֲפִלּוּ רָאָה הָעֲנָבִים יוֹצְאוֹת מִכֶּרֶם עָרְלָה אוֹ יָרָק יוֹצֵא מִן הַכֶּרֶם לוֹקֵחַ מֵהֶן. וְהוּא שֶׁלֹּא יִרְאֶה אוֹתוֹ בּוֹצֵר מִן הָעָרְלָה אוֹ לוֹקֵט הַיָּרָק בְּיָדוֹ:
When there is a doubt whether produce is orlah or kilai hakerem in Eretz Yisrael, it is forbidden. In Syria, i.e., the lands that David conquered, it is permitted. What is implied? If there was a vineyard [containing] orlah and grapes were being sold outside it, or there were vegetables sown inside it and vegetables were being sold outside it, [in which instance,] there is a doubt whether [the grapes or the vegetables] came from it or from another place, in Syria, they are permitted. In the Diaspora, even if one sees grapes being taken out from a vineyard that is orlah or vegetables being taken out from a vineyard, one may purchase them provided one does not actually see orlah being reaped or the vegetables being harvested [from the vineyard].
