In the dead of night, within an isolated cave, a complex event of survival, moral ambiguity, and hidden providence unfolds. Convinced that the entire world has been destroyed, Lot's daughters give their father wine in a desperate bid to preserve human life and establish a lineage.
The text hints at a deeper layer of divine involvement during this night. While some explain the phrasing simply indicates the daughters did not care which specific night the event took place, focusing only on the act of drinking [מלבי״ם], or view it as a mere grammatical anomaly [ביאור יש״ר], the primary approach among commentators is that the language points directly to God. Even though the daughters might have brought wine with them from Sodom [ביאור שטיינזלץ], the prevailing view is that God miraculously provided the wine for them inside the cave. This hidden providence was designed to bring forth the nations of Ammon and Moab, ultimately paving the way for the Davidic dynasty and the Messiah [רש״י, רבנו בחיי, גור אריה, פני דוד].
A sharp contrast exists between how the two sisters approached the act. The older daughter initiated the plan and felt no shame in her actions, a brazenness she later cemented by openly naming her son Moab, meaning from the father. Because of her lack of shame, her actions are recorded explicitly and actively, without masking the disgrace. The younger sister, however, felt deep shame and sought to conceal the act, naming her son Ben-ammi to hide the origin. Consequently, her actions are described with gentler, cleaner language [רש״י, מלבי״ם, גור אריה].
The older daughter's true motives are a subject of debate. On one hand, she received historical reward for her swiftness in performing what she believed was a Commandment to sustain humanity. On the other hand, her initiative and her decision to instruct her sister are viewed as the beginnings of harlotry. A synthesized view suggests that while her overarching goal was indeed directed toward heaven, the act itself became tainted by an awakened lust [מזרחי, ריב״א, תורה תמימה, חזקוני, פרדס יוסף].
Regarding Lot's own awareness, the straightforward reading suggests he was so heavily intoxicated that he felt absolutely nothing, perhaps believing the entire episode was merely a dream brought on by his own thoughts [רד״ק, שד״ל]. However, an ancient scribal tradition places a special mark over the text describing when the older daughter arose. Such marks indicate an intermediate state between writing and erasure, demanding a nuanced reading [הכתב והקבלה]. Most commentators deduce from this that while Lot was completely oblivious when his daughter lay down, he possessed some level of awareness when she got up [רש״י, מנחת שי, קיצור בעל הטורים].
Opinions vary on the extent of his realization. He may have vaguely felt her rising from his sleep [רלב״ג], or perhaps he saw her in his bed the next morning without being certain if anything had actually occurred [גור אריה, שפתי חכמים, דברי דוד, משכיל לדוד]. Others suggest he only connected the pieces later when his younger daughter began serving him wine [יריעות שלמה].
This partial awareness leads to severe criticism of Lot. If he suspected what had happened, he should have guarded himself against getting drunk the following night. Instead, he allowed it to happen again. Commentators note that Lot harbored a deep desire for forbidden relations. Although he considered himself righteous and deceived himself to avoid confronting his own flaws, his subconscious drove him to repeat the sin. While his daughters acted with the intention of fulfilling a Commandment and preserving the world, Lot surrendered to his lust. This dynamic illustrates how the righteous walk upright in their deeds while transgressors stumble in those exact same actions, demonstrating that a person consumed by forbidden desires is ultimately fed his own flesh [רש״י, רד״ק, תורה תמימה, קונטרס חיבה יתירה].
