“Lot’s two daughters conceived from their father” (Genesis 19:36). “Lot’s two daughters conceived from their father” – Rabbi Elazar said: A woman never conceives from her initial act of intercourse. But is it not written: “Lot’s two daughters conceived from their father”? (Genesis 19:36). Rabbi Tanḥuma said: They manipulated themselves, broke their hymen, and conceived as though it were from a second act of intercourse.
Rav Naḥman bar Ḥanin said: Anyone who has a ravenous appetite for sexual relations will ultimately be fed his own flesh.23A metaphor for incest. Rabbi Yudan of Gaul and Rabbi Shmuel bar Naḥman, both in the name of Rabbi Elyehoeini: We do not know whether Lot lusted after his daughters or his daughters lusted after him. From what is written: “The isolated one24Lot, who was isolated from Abraham. seeks lust” (Proverbs 18:1), we see that Lot lusted after his daughters, but his daughters did not lust after him.
Rabbi Tanḥuma bar Rabbi Ḥiyya in the name of Rabbi Hoshaya the interpreter: There is no Shabbat on which one does not read the passage about Lot.25In those days there was apparently a practice to recite the passage about Lot every Shabbat, to warn people not to overindulge in wine. What is the source for this? “The isolated one seeks lust, with all tushiya26Tushiya is a reference to Torah (see Sanhedrin 26a). he will be exposed”27The shame of Lot is exposed for all to reflect upon. (Proverbs 18:1).
Rabbi Aḥa said: “They will be exposed” is not written here, but rather, “he will be exposed” – the men [of Amon and Moav] were distanced, but the women were drawn near.28The shame of Lot is preserved for all time, in that the Torah prohibits Moavite and Amonite men from marrying Israelite women (Deuteronomy 23:4). The shame of Lot’s daughters is not preserved, however, because Moavite and Amonite women may marry Israelite men.
