Chapter 11 of 17 in Forbidden Foods — 26 halachot
Halacha 1א׳
יַיִן שֶׁנִּתְנַסֵּךְ לְעַכּוּ"ם אָסוּר בַּהֲנָיָה. וְהַשּׁוֹתֶה מִמֶּנּוּ כָּל שֶׁהוּא לוֹקֶה מִן הַתּוֹרָה. וְכֵן הָאוֹכֵל כָּל שֶׁהוּא מִתִּקְרֹבֶת עַכּוּ"ם מִבָּשָׂר אוֹ מִפֵּרוֹת אֲפִלּוּ מַיִם וּמֶלַח הָאוֹכֵל מֵהֶן כָּל שֶׁהוּא לוֹקֶה שֶׁנֶּאֱמַר (דברים לב לח) "אֲשֶׁר חֵלֶב זְבָחֵימוֹ יֹאכֵלוּ יִשְׁתּוּ יֵין נְסִיכָם יָקוּמוּ" וְגוֹ':
Wine that was poured as a libation to idolatry is forbidden for benefit, and one who drinks of it, any amount whatever, is flogged by Torah law. And likewise one who eats any amount whatever of what has been offered to idolatry, whether of flesh or of fruit — even water and salt — one who eats of them any amount whatever is flogged, as it is said (Deuteronomy 32:38), "who ate the fat of their sacrifices, drank the wine of their libations; let them rise up," and so forth.
Halacha 2ב׳
יַיִן שֶׁנִּתְנַסֵּךְ לָהּ כְּזֶבַח שֶׁקָּרֵב לָהּ וְכֵיוָן שֶׁאִסּוּר זֶה מִשּׁוּם עַכּוּ"ם הוּא אֵין לוֹ שִׁעוּר שֶׁנֶּאֱמַר בַּעֲבוֹדַת כּוֹכָבִים וּמַזָּלוֹת (דברים יג יח) "וְלֹא יִדְבַּק בְּיָדְךָ מְאוּמָה מִן הַחֵרֶם":
Wine that was poured as a libation to it is like a sacrifice that was offered to it; and since this prohibition is on account of idolatry, it has no minimum measure, as it is said concerning the worship of the stars and the constellations (Deuteronomy 13:18), "and nothing of the devoted thing shall cleave to your hand."
Halacha 3ג׳
יֵין הָעַכּוּ"ם שֶׁאֵין אָנוּ יוֹדְעִין אִם נִתְנַסֵּךְ אוֹ לֹא נִתְנַסֵּךְ וְהוּא הַנִּקְרָא סְתַם יֵינָם אָסוּר בַּהֲנָאָה כְּמוֹ יַיִן שֶׁנִּתְנַסֵּךְ. וְדָבָר זֶה מִגְּזֵרוֹת סוֹפְרִים הוּא. וְהַשּׁוֹתֶה מִסְּתַם יֵינָם רְבִיעִית מַכִּין אוֹתוֹ מַכַּת מַרְדּוּת:
The wine of gentiles, of which we do not know whether it was poured as a libation or was not poured as a libation — and this is what is called setam yeinam — is forbidden for benefit, like wine that was poured as a libation. And this matter is among the decrees of the Scribes. And one who drinks a quarter-log of setam yeinam is struck with lashes of rebellion.
