(Note: On the truth which lay at the foundation of this idea of the unity of the soul and blood, which others of the ancients shared with the Hebrews, particularly the early Greek philosophers, see Delitzsch's bibl. Psychol. pp. 242ff. "It seems at first sight to be founded upon no other reason, than that a sudden diminution of the quantity of the blood is sure to cause death. But this phenomenon rests upon the still deeper ground, that all the activity of the body, especially that of the nervous and muscular systems, is dependent upon the circulation of the blood; for if the flow of blood is stopped from any part of the body, all its activity ceases immediately; a sensitive part loses all sensation in a very few minutes, and muscular action is entirely suspended... The blood is really the basis of the physical life; and so far the soul, as the vital principle of the body, is pre-eminently in the blood" (p. 245).)

- Lastly (Leviticus 17:15, Leviticus 17:16), the prohibition against eating "that which died" (Leviticus 11:39-40), or "that which was torn" (Exodus 22:30), is renewed and supplemented by the law, that whoever, either of the natives or of foreigners, should eat the flesh of that which had fallen (died a natural death), or had been torn in pieces by wild beasts (sc., thoughtlessly or in ignorance; cf. Leviticus 5:2), and neglected the legal purification afterwards, was to bear his iniquity (Leviticus 5:1). Of course the flesh intended is that of animals which were clean, and therefore allowable as food, when properly slaughtered, and which became unclean simply from the fact, that when they had died a natural death, or had been torn to pieces by wild beasts, the blood remained in the flesh, or did not flow out in a proper manner. According to Exodus 22:30, the נבלה (that which had fallen) was to be thrown to the dogs; but in Deuteronomy 14:21 permission is given either to sell it or give it to a stranger or alien, to prevent the plea that it was a pity that such a thing should be entirely wasted, and so the more effectually to secure the observance of the command, that it was not to be eaten by an Israelite.
