Exodus 22:30

ואנשי קדש תהיון לי AND YE SHALL BE MEN OF HOLINESS UNTO ME — If you will be holy and keep yourselves aloof from the loathsomeness of carrion and Trefa you are Mine, if not you are not Mine (cf. Mekhilta). ובשר בשדה טרפה [NEITHER SHALL YE EAT] ANY FLESH THAT IS TORN IN THE FIELD – The same holds good in case the animal has been torn in the house, only that Scripture speaks of what usually happens mentioning the field because it is the place where it is usual for cattle to be torn. A similar instance is, (Deuteronomy 22:27) “for he found her in the field”, but the same law would apply if he found her elsewhere. Another example is, (Deuteronomy 23:11) “Any man that is unclean by reason of uncleanliness that chanceth him by night”; the same law, however, applies to an uncleanliness that happens by day, but night is mentioned because Scripture speaks of what usually happens (Mekhilta). The Targum renders ובשר בשדה טרפה by ובשר תליש מן חיוא חיא “flesh that is torn off from a living animal”, i. e. flesh that has been torn off through a laceration caused by a wolf or a lion, from a living beast which is permitted to be eaten (e. g., a stag), or from cattle permitted to be eaten. לכלב תשלכון אתו YE SHALL CAST IT TO THE DOGS — You may give it to a heathen as well as to the dog. Or, perhaps this is not so, but כלב is to be taken literally? Scripture, however, states with regard to carrion, (Deuteronomy 14:21) “Thou shalt give it to a stranger or sell it unto an alien”, from which it follows by a conclusion à fortiori that you may derive whatever benefit you like from the Trefa (and so you also may give it to heathen). But if this be so, what is the force of Scripture expressly saying “to the dog”? It is to teach you that the dog is to be given preference in this respect and Scripture tells you at the same time that God does not withhold the reward due to any of His creatures. The dog is entitled to reward because it is stated, (Exodus 11:7) “But against the children of Israel shall not a dog move its tongue”, and this happened. The Holy One, blessed be He, said: Give it the reward it deserves (Mekhilta).

וְאַנְשֵׁי־קֹ֖דֶשׁ תִּהְי֣וּן לִ֑י וּבָשָׂ֨ר בַּשָּׂדֶ֤ה טְרֵפָה֙ לֹ֣א תֹאכֵ֔לוּ לַכֶּ֖לֶב תַּשְׁלִכ֥וּן אֹתֽוֹ׃ {ס}        

And you shall be holy men to me: neither shall you eat any meat that is torn of beasts in the field; you shall cast it to the dogs.
