Mishnah Temurah 6:1: Everything that is forbidden [from being offered] on the altar is forbidden in any amount. [The things that are forbidden are:] an animal with which a woman committed bestiality, an animal with which a man committed bestiality, an animal set aside, an animal which was worshipped, a prostitute's fee, a dog's exchange, a Kilaim, a Treifah [an animal with a mortal condition such that it would die within one year], and [an animal] delivered by Caesarean section. What is a "set aside"? An animal set aside for idol worship. It is forbidden, but that which is upon it is permitted. What is a worshipped [animal]? All that serve it. It and that which is upon it is forbidden. Both this [the set aside] and this [the worshipped animal] may be eaten.

So too is the one who says to his friend, "Take this lamb and your maidservant will sleep with my slave," Rebbe says, "This is not a prostitute's payment." The Sages say, "It is a prostitute's payment."
