Why does the Torah write "Demeihem bam" - in the plural?
Rashi: To incorporate the animal that raped in the Din of Sekilah.
Having taught us that a bestiality is punishable Chayav Misah in Kedoshim, why does the Torah repeat it here?
Sanhedrin, 16a: 'Im Eino Inyan' for the person, it refers to the animal, and the Torah writes "Shochev" to compare Nishkav to Shochev inasmuch as, like a person who lies with an animal, a person who brings an animal on himself requires a Beis-Din of twenty-three to sentence him to death. 1
See Torah Temimah, note 191.
Why did the Torah juxtapose the Parshah of bestiality to that of Mechashef?
Hadar Zekenim (in Pasuk 17): Because witches can turn a woman into an animal [and be intimate with her, like the case of someone who [purchased a donkey, and] found that he was riding on a woman in the market (Sanhedrin 67b).
