Blood, Sex, and Gore in the Hebrew Bible Session 2 - Sodom and Gemorrah

ואת זכר לא תשכב, “and you are not to indulge in homosexual relations with another male.” Nachmanides writes that the reason for the injunctions against sexual relations between males, and between man and beasts, are quite clear, seeing that G’d abhors such mismatching of His creatures. Such relations cannot contribute to the continued existence of the respective species, the only valid reason for indulging in the sexual act. Ibn Ezra writes that seeing that the older daughter of Lot said to her younger sister (Genesis 19,34) “here I have slept with my father last night, etc.,” this is clear proof that the Torah views initiation of the act by the female of the species as on the same level as if the male initiates it, i.e. when a forbidden relationship is entered into both parties are equally culpable. Although the Torah uses the masculine לא תשכב in our verse, the same applies to the female of the spies, i.e. lesbianism is also prohibited. Nachmanides criticizes Ibn Ezra, saying that if he were correct why was the woman not automatically included in the warning of ובכל בהמה לא תתן שכבתך לטמאה בה, “you must not inject your seed into any female animal to lie with it carnally,” and mention separately immediately afterwards:ואשה לא תעמוד לפני בהמה לרבעה, “and a woman must not stand in front of an animal for the purpose of mating, etc,?” He therefore concludes that the verse quoted by Ibn Ezra from Genesis 19,34 means that Lot’s daughter drew attention to the fact that seeing that ejaculation of semen by the male normally occurs only as a result of physical activity by the male, something which in the case of the drunken Lot could hardly be expected, she told her sister that in order to secure the semen that both of them wanted, it was not enough to remain passive during the procedure, but they had to be physically active to arouse their father.
