(יד) לֹא־תְקַלֵּ֣ל חֵרֵ֔שׁ וְלִפְנֵ֣י עִוֵּ֔ר לֹ֥א תִתֵּ֖ן מִכְשֹׁ֑ל וְיָרֵ֥אתָ מֵּאֱלֹהֶ֖יךָ אֲנִ֥י יְהֹוָֽה׃
(14) You shall not insult the deaf, or place a stumbling block before the blind. You shall fear your God: I am the LORD.
וַהֲרֵי אֵבֶר מִן הַחַי, דִּכְתִיב ״לֹא תֹאכַל הַנֶּפֶשׁ עִם הַבָּשָׂר״, וְתַנְיָא, רַבִּי נָתָן אוֹמֵר: מִנַּיִן שֶׁלֹּא יוֹשִׁיט אָדָם כּוֹס יַיִן לְנָזִיר וְאֵבֶר מִן הַחַי לִבְנֵי נֹחַ — תַּלְמוּד לוֹמַר ״וְלִפְנֵי עִוֵּר לֹא תִתֵּן מִכְשֹׁל״, הָא לִכְלָבִים — שְׁרֵי!
The Gemara further challenges Rabbi Abbahu’s opinion: And yet there is the prohibition against eating a limb cut from a living animal, as it is written: “Only be steadfast in not eating the blood; for the blood is the life; and you shall not eat the life with the flesh” (Deuteronomy 12:23). And it was taught in a baraita that Rabbi Natan says: From where is it derived that a person may not offer a cup of wine to a nazirite, who is prohibited from drinking wine, and that he may not offer a limb cut from a living animal to a descendant of Noah, who is prohibited by Noahide law from eating a limb from a living animal? The verse states: “You shall not put a stumbling block before the blind” (Leviticus 19:14). Causing another person to sin is like placing a stumbling block before a blind person; one who does so violates this prohibition. The prohibition of giving a limb from a living animal to a gentile is apparently due only to the prohibition of placing a stumbling block. However, it is permitted for one to throw it to dogs. Therefore, despite the fact that the verse says: “You shall not eat it,” apparently there is no prohibition against benefiting from this prohibited item. This challenges Rabbi Abbahu’s principle.
