Avodah Zarah4: 12
הַמְטַהֵר יֵינוֹ שֶׁל עוֹבֵד כּוֹכָבִים וְנוֹתְנוֹ בִרְשׁוּתוֹ, וְהַלָּה כוֹתֵב לוֹ: הִתְקַבַּלְתִּי מִמְּךָ מָעוֹת — מֻתָּר. אֲבָל אִם יִרְצֶה יִשְׂרָאֵל לְהוֹצִיאוֹ, וְאֵינוֹ מַנִּיחוֹ עַד שֶׁיִּתֶּן לוֹ אֶת מְעוֹתָיו — זֶה הָיָה מַעֲשֶׂה בְבֵית שְׁאָן, וְאָסְרוּ חֲכָמִים.
[If] one prepares an idolater’s wine in purity and places it in his domain, and this one writes to him, “I have received [the] money from you” —- it is permitted. But if the Jew would want to remove it, and he does not allow him [to do so] until he gives him his money —- this was [once] an incident in Beis Shean, and the Sages forbade [it].
