Kaisipang Hudyo sa Exodo 22:30: Yesod Mora VeSod HaTorah, Nineteen Letters & Guide for the Perplexed

And there are commandments that include matters of permission, such as "to the stranger who is within your gates you may sell" (Deuteronomy 14:21) and "you shall cast it to the dog" (Exodus 22:30), for the reasoning is connected to "And you shall be holy men to Me." Regarding torn flesh, it is not meant for your consumption but should be thrown to the guarding dog of your flock. Therefore, we learn from the tradition that it would always appear this way to them (the Israelites). "In them, you shall serve" (Exodus 20:5), for all the commandments were handed down from the hands of the forefathers, and there is no distinction between the words of the commandments and the words of the Torah, for both were given to us, and they received them from their forefathers, and their forefathers received them from the prophets, and everything came from the mouth of the Almighty through Moses.

Mishpatim. — Judgments or Principles of Justice. — All these ideal theories have only value, however, if thou really livest, as thou hast gained the conception, in a Divine world, with Divine powers, man-Israel. The first requisite is, Justice! Respect every being around thee and all that is in thee as the creation of thy God; everything belonging to them as given them by God or in accordance with law which He has sanctioned. Leave willingly to each being that which it is justly entitled to call its own. Be not as regards aught a curse. Especially honor every human being as thy equal, regard him in his essence, that is to say, in his invisible personality, in his bodily envelope and in his life. Extend the same regard to his artificially enlarged body, his property; to the demands which he may be entitled to make upon you for assistance by grants of property or acts of physical strength; in measure and number; in recompense of injury to his person or possessions. Have regard, also, to his rightful claim of truth; of liberty, happiness, and peace of mind, of honor and undisturbed tranquillity. Do not abuse his weakness of heart, mind, or body; do not unjustly employ thy legal power over him.

Blood (Lev. 17:12), and nebelah, i.e., the flesh of an animal that died of itself (Deut. 14:21), are indigestible, and injurious as food; Trefah, an animal in a diseased state (Exod. 22:30), is on the way of becoming a nebelah.
