Exodus 22:31

Cast - Worn-out; old; cast-off.

Neither shall ye eat - flesh - torn of beasts in the field - This has been supposed to be an ordinance against eating flesh cut off the animal while alive, and so the Syriac seems to have understood it. If we can credit Mr. Bruce, this is a frequent custom in Abyssinia; but human nature revolts from it. The reason of the prohibition against eating the flesh of animals that had been torn, or as we term it worried in the field, appears to have been simply this: That the people might not eat the blood, which in this case must be coagulated in the flesh; and the blood, being the life of the beast, and emblematical of the blood of the covenant, was ever to be held sacred, and was prohibited from the days of Noah. See Clarke's note on Genesis 9:4.

In the conclusion of this chapter we see the grand reason of all the ordinances and laws which it contains. No command was issued merely from the sovereignty of God. He gave them to the people as restraints on disorderly passions, and incentives to holiness; and hence he says, Ye shall be holy men unto me. Mere outward services could neither please him nor profit them; for from the very beginning of the world the end of the commandment was love out of a pure heart and good conscience, and faith unfeigned, 1 Timothy 1:5. And without these accompaniments no set of religious duties, however punctually performed, could be pleasing in the sight of that God who seeks truth in the inward parts, and in whose eyes the faith that worketh by love is alone valuable. A holy heart and a holy, useful life God invariably requires in all his worshippers. Reader, how standest thou in his sight?

The sanctification of the nation was emphatically symbolized by strictness of diet as regards both the kind of animal, and the mode of slaughtering. See Leviticus 11; 17.

22:31 Ye shall be holy unto me - And one mark of that honourable distinction is appointed in their diet, which was, that they should not eat any flesh that was torn of beasts - Both because the blood was not duly taken out of it, and because the clean beast was ceremonially defiled, by the touch of the unclean.
