Original Torah: Ancient Words in a Modern Light

• One, is that this is probably not what the Torah meant, since it’s redundant. However, as the original meaning of the text was not paramount to the Rabbis, I can let it slide.
• Two, BZ learns from the categories of the list that the topic is incestuous or adulterous relationships. However, the list also includes bestiality, sex with a menstruant, and leaves out the man’s daughter, nieces, and wife of his mother’s brother.
• In context, the verse is bookended by prohibitions of being like the following nations 18:1-4 and 20:22-26. I would need to be convinced that the Torah approved of non-incestuous same-sex relationships. Whether this impacts on his midrash I have not yet decided.

In any case, bravo on a brilliant understanding of the text using classical methods.
Mah Rabu:

Likewise, Leviticus 18:22 (by way of the kelal ufrat uchlal that we have explained above) constructs the prototype that mishkevei ishah refers specifically the incestuous and adulterous relationships of the sort listed in Leviticus 18, so that Leviticus 20:13 can also be understood to refer only to these categories of same-sex relationships.
