BESTIALITY
Sexual sin quite common among the Canaanites (Lev. 18:23-25), the Egyptians (Herodotus, II, 46, speaks of the sacred goat of Mende, used for such a practice as a religious rite).
In Israel it was punished with death, both of the human person and of the animal (Ex. 22:18; Lev. 20:15 ff.; cf. Deut. 27:21).
