Avodah Zarah 70 - August 27, 3 Elul

Rava ruled that if a Jew is with a non-Jewish prostitute and there is wine present, one can assume that the Jew ensured the prostitute did not come into contact with the wine, and therefore it is permitted. Although he may not be able to control his sexual desires, he is not presumed to be lax in the laws of yayin nesech (forbidden wine). However, in the reverse case—where a Jewish prostitute is with a non-Jew—since the non-Jew holds the dominant position in the relationship, we assume she has no way to prevent him from touching the wine, and thus it is forbidden. There are nine different cases in which a Jew's wine was left with a non-Jew, and Rava issued rulings on whether the wine was permitted or forbidden in each instance. In many of these cases, he permitted the wine based on his assessment that the non-Jew would likely not have touched it, due to the possibility of being caught by the owner or another Jew. In other cases, there was uncertainty about whether the non-Jew had even come into contact with the wine, or whether the individuals present were Jews or non-Jews. Two additional cases were brought before other rabbis. In the second case, Abaye introduces a comparison to the laws of impurity, and the Gemara addresses this comparison. It notes that the rabbis were stricter regarding impurity laws than they were with wine, citing a debate between Rav and Rabbi Yochanan to support this point. Three challenges are raised against the positions of Rav and Rabbi Yochanan—two against Rav and one against Rabbi Yochanan—and each is resolved.
