John Gill's Exposition of the Whole Bible
Leviticus 18:23
Neither shall thou lie with any beast, to defile thyself therewith,.... A female one, as Aben Ezra notes, as a mare, cow, or ewe, or any other beast, small or great, as Ben Gersom, or whether tame or wild, as Maimonides b; and even fowls are comprehended, as the same writers observe:
neither shall any woman stand before a beast to lie down thereto: that is, stand before a beast, and by a lascivious and obscene behaviour solicit the beast to a congress with her, and then lie down after the manner of four-footed beasts, as the word signifies, that it may have carnal copulation with her: for a man to lie with a beast is most shocking and detestable, but for a woman to solicit such an unnatural mixture is most horrible and astonishing: perhaps reference may be had to a most shocking practice among the Egyptians, from among whom the Israelites were lately come, and whose doings they were not to imitate,
Leviticus 18:3; and which may account for this law, as Bishop Patrick observes: at Mendes, in Egypt, a goat was worshipped, as has been remarked Leviticus 18:7; and where the women used to lie with such creatures, as Strabo c and Aelianus d from Pindar have related; yea, Herodotus e reports, of his own knowledge, that a goat had carnal copulation with a woman openly, in the view of all, in his time; and though that creature is a most lascivious and lustful one, yet, as Bochart f from Plutarch has observed, when it is provoked by many and beautiful women, is not inclined and ready to come into their embraces, but shows some abhorrence of it: nature in brutes, as that learned man observes, is often more prevalent in them than in mankind:
it [is] confusion; a mixing of the seed of man and beast together, a blending of different kinds of creatures, a perverting the order of nature, and introducing the utmost confusion of beings, from whence monsters in nature may arise.
