Rava of Parzakya said to Rav Ashi: From where is this matter that the Sages stated derived, that
licentiousness does not apply
with regard to an animal? Rav Ashi replied that it is
as it is written: “You shall not bring the hire of a harlot, or the price of a dog, into the house of the Lord your God for any vow; for both of them are an abomination to the Lord your God” (
Deuteronomy 23:19). This verse prohibits one from sacrificing an animal that served as payment to a prostitute or as payment for the purchase of a dog.
And it is taught in a mishna (
Temura 30a): In the converse cases,
the hire of a dog, i.e., a
kosher animal that was given to the owner of a dog as payment for engaging in intercourse with it,
and the price of a prostitute, i.e., a kosher animal which served as payment in the purchase of a maidservant acquired for prostitution,
are permitted to be sacrificed,
as it
is stated in the aforementioned verse:
For both of them. This term indicates that only those
two animals may not be sacrificed, i.e., those which served as the hire of a harlot and as the price of a dog;
and not four animals, as the reverse cases are excluded from this
halakha. This indicates that the concept of licentiousness does not apply with regard to animals, as the payment for intercourse with a dog is not considered payment for prostitution.
