Rashi: "Esnan Zonah" is the lamb (for example) that one pays a Zonah for her services.

Temurah, 29a: If someone says to a prostitute 'Here is a lamb as payment for your services!' or if he says to his friend 'Take this lamb and let your Shifchah spend the night with my Eved Ivri!' ¹

Temurah, 29b: It is a woman whose marriage would be prohibited. ¹ Consequently, it incorporates all Arayos (including married women and women who are subject to incest, all of whom are subject to Kares) with the sole exception of one's own wife who is a Nidah. ²

Temurah, 29b: The Torah writes specifically "Esnan Zonah" to preclude that of a male.

Rashi: "M'chir Kelev" is the lamb that one swapped for a dog.

Moshav Zekenim: It includes any Kasher animal traded for any Tamei animal. The Torah mentioned a dog because it is common to use them for guarding, and sometimes one trades it for a lamb or a kid-goat.

Temurah, 30a: Where Reuven says to Shimon 'Take this lamb as payment for your dog! Similarly, where they are partner, and where he takes ten lambs and Shimon, nine lambs and one dog - all the lambs that Shimon takes are considered 'M'chir Kelev', and may not be brought as a Korban. ¹

Sifri: We learn via a Gezeirah Shavah "To'evah" "Ki To'evah hi" in Parshas Shofrim, 17:1 in connection with sacrificing Ba'alei-Mumin, that it entails actually bringing the animl on the Mizbe'ach - not just bring it to the Azarah.

Temurah, 30b: It incorprates donating gold to overlay any part of the Beis-Hamikdash - such as behind the Kodesh Kodshim - in the prohibition of bringing Esnan Zonah and M'chir Kelev to the Beis-Hamikdash. ¹

Avodah Zarah, 46b: It implies that the prohibition of bringing Esnan Zonah and M'chir Kelev to the Beis-Hamikdash applies both to things that are detached to the gound and to what is attached.

Targum Yonasan: It includes bringing an Esnan Zonah or M'chir Kelev even for a voluntary Neder, how much more so for a Korban that one is obligated to bring. ¹

Temurah, 30b: It includes birds in the prohibition, ² and to preclude Kodshim animals, which are already Nadur. ³

Sifri: It incorporates the Bamah in the prohibition of "Lo Savi ... el Beis Hashem". ⁴

Ramban: Because the Zonah tries to atone for her misdeeds by performing Mitzvos with the proceeds of her earnings, ¹ thereby justifying her actions and encouraging herself to continue doing them.

Alshich: It is like a Mitzvah that comes through an Aveirah.

Oznayim la'Torah: Because Z'nus is the antithesis of Kedushah. ²

Ramban #1: This is based on the fact that hunters and those who guard the walls tend to keep ferocious dogs that wreak havoc among the public, and they, like the prostitute, attempts to atone for their misdeeds by performing Mitzvos with the proceeds of the sale of their dogs. ¹

Ramban #2 (citing the Ibn Ezra): Because it is disgraceful to bring the exchange of a dog (or the wages of a prostitute) on the Mizbe'ach. ²

K'li Yakar: Because, since dogs mate in public, they are compared to a Zonah regarding Z'nus and brazenness. Consequently, like Esnan Zonah, it is inappropriate to bring them to a place of Kedushah, which is a fence against Ervah, and the Tzitz atones for brazenness.

Oznayim la'Torah: Because people befriend dogs over and above all other species of animals - wasting time and money on pampering them. Moreover they do this because the dogs protect them, in spite of the fact that they (the dogs) do not draw a distinction between friend and foe - and attack anyone they can lay their fangs on. ³

Refer to 23:19:2:1:1.

Sifri: To restrict the prohibition to what he pays her for her services, bu not to what he pays her for loss of work.

Rashi: They include where the object has been changed
