זה הדבר, when the Torah said in 15,31 והזהרתם את בני ישראל מטומאתם, “you are to warn the Israelites regarding their state of ritual contamination,” the warning implied that they were to separate themselves from spiritually negative influences represented both by ritual contamination and by demons.

דם יחשב, as if the relationship of man to the animals were as it had been before the deluge when it had been forbidden to kill animals as food.

חקת עולם תהיה זאת, not to offer sacrifices to the demons even though they were not being equated with deities in any manner, but were considered only as creatures that could be employed by their human masters. They even used to employ such demons for errands to distant countries. We have documented proof of this in the case of Joseph Shida [the demon named Joseph].(Sanhedrin 59, compare Nachmanides) and about the demon who was prominent in the household of Rav bar Rav Ashi (Chulin 105). Had such demons been considered deities it is inconceivable that people of Rav Ashi’s stature or Rav Pappa’s stature would have had any track with them whatsoever. It is reported in the Talmud that whereas little is known about the manner of these demons’ creation, they are known to eat and drink just as human beings. It is further worthy of mention that the sages, collectively, referred to the phenomenon of the demons as מזיקים, destructive, harmful phenomena. They multiply in a manner similar to humans and they die a regular death. They see without being seen themselves. Apparently, although they are composed of composite material, their bones are extremely thin and transparent. The author speculates that just as ordinary human beings in common with the animals possess a נפש חיוני “intangible life-force” which, seeing that it dies with the body it inhabits, as distinct from the human נשמה which is an intangible spirit emanating in the celestial regions, is basically terrestrial in nature, these demons are “powered” by such a life-force. The reason we find that “life-force” referred to on occasion as נפש is the fact that it cannot exist without its tangible partner, the one which feeds on food and drink secured from what is available in our terrestrial universe. Consider the very fact that the Torah describes “blood as the life-force” (Deuteronomy 12,23). If someone were to sacrifice blood to such a creature, especially, seeing that it is powerful enough to sustain the life of such creatures, the blood sacrificed to such creatures would be equivalent to keeping these demons alive. (compare Maimonides, Moreh Nevuchim,3,46 on the subject). This would be a violation of the statement in Chulin 105 כל מידי דצייר וחתים וכייל ומני לית לן רשותא למשקל מינעה. This is a conversation between the “owner” of a demon, Mar bar Rav Ashi, according to which the demon who had not paid back a loan on time to the “owner” claimed that his power to collect objects in this world did not include objects which were clearly defined and visible. From this Tossaphot Taanit 8 divrey hamatchil אלא בדבר concludes that if clearly defined and visible phenomena in this world were out of bounds to the demons unless they were definitely ownerless, phenomena which are not visible to us humans belonged to the category of phenomena over which such demons did have control. At any rate, when a situation exists when many people find such demons useful and pliable to their wishes, people indulged in offering them blood so as to endear themselves to these creatures and to get them to perform their wishes. The people offering these gifts of blood used to eat it themselves also, in order to share more common ground with these creatures. Some people even made a point of consuming the blood of such “gifts” to the demons in the vicinity of the Temple. They were under the impression that these demons were performing their dances in that vicinity. They hoped to ingratiate themselves with these creatures by showing them this kind of “respect.” When G’d decided to sanctify us and He separated His people from dependence on such demons and taught us not to pursue such ultimately useless phenomena and put our trust in them, seeing that contrary to a superficial perception they are really mazikim, destructive forces, as our sages correctly described them, He levied a severe penalty on people who continue such relationships as they used to entertain with demons. The penalty of karet means severance from one’s own people’s eternal future. (verse 10) G’d levied a similar penalty on eating blood and offering gifts to these demons as He had levied at the time in Gan Eden when he forbade eating from the tree of knowledge on pain of man becoming mortal, i.e. losing an aspect of his infinity on this earth. (Genesis 2,17). The Torah rationalized its prohibition and the severity of the penalty by stating: “for the soul (intangible life-force) of the flesh is in the blood.” This is the Torah’s way of referring to the almost invisible essence of these creatures. On the one hand, this essence is called nefesh “life-force,” on the other hand it is referred to as blood, as once the blood stops coursing through the veins of the body it feeds it is the end of the existence of both the body and life force of such creatures. G’d added (verse 11) ואני נתתיו לכם על המזבח לכפר, “I have given you an opportunity to present this blood on My altar in order to facilitate your atonement for your life-force. The point G’d is making is that as opposed to these demons for whom such blood is an essential part of their nutrients, enabling them to stay alive, I, the Lord, do not need anything like this for Myself; on the contrary, I have provided you My people with an opportunity to remain alive yourselves by achieving atonement for your sins by means of sacrifices involving the life blood of the animal you are offering. Sacrifices, offerings, in order to be meaningful as expiation, must be in a certain reciprocal relationship to the donor. If the donor had been guilty of forfeiting his life, only someone else’s life, in this instance the blood of the sacrificial animal, can possibly achieve this kind of atonement in lieu of the sinner’s lifeblood himself. Other parts of the sacrificial animal being burned up on the altar, similarly, correspond to the parts of the body of the donor which had been guilty of committing the sin for which the donor hopes to atone. (compare author on Leviticus 1,2)

אשר יצוד ציד. Seeing that in the main, these free roaming beasts’ habitat is in desolate regions of the earth, areas in which the kind of demons we mentioned are at home, (compare Isaiah 13,21 “there ostriches shall make their home and there shall satyrs (demons) dance.”) the Torah therefore forbids to leave the blood of these beasts exposed and ordered us to cover it with earth in order to forestall any chance that this blood be used to feed the demons. It goes on to say:

כי נפש כל בשר דמו בנפשו הוא, “for the life-force of all living creatures is its blood” [or contained with its blood. Ed.] (a reference to the way the author described such an almost invisible essence in the blood in his commentary on verse 7).

בנפשו, including this invisible life-force contained therein. This is because the blood contains something almost intangible. Seeing this ingredient is the closest to anything completely intangible in this terrestrial universe, it is an ideal nutrient for the demons and for those who consort with them. The Torah says:

ואומר לבני ישראל, although I have permitted the gentiles the consumption of such lifeblood, I have prohibited it to the Children of Israel already in Leviticus 7,26 seeing that the life essence of living creatures is contained in it while the animal was alive and it is liable to transfer some of these animalistic characteristics kind to the persons ingesting it as food. The Torah wants to protect the Jewish people from absorbing more animalistic tendencies than we already possess.

וכל נפש אשר תאכל נבלה וטרפה, after the Torah wrote about the prohibition of eating blood, something which if permitted would draw us closer to the circle of demons, it speaks about the prohibition of eating meat from diseased animals or animals which have died of causes other than ritual slaughter. A nation that concentrates on attracting the holy spirit to itself would do something counterproductive if consuming such carcasses which are the home base of spiritually negative influences. We know that this is so from the Torah’s prohibition of trying to derive spiritual inspiration from the dead or parts of them. (compare Deuteronomy 18,11 where consulting ghosts or other death-related matters is specifically outlawed, and we are ordered not to tolerate people who practice such cults in our land.)

ונשא עונו. In accordance with the degree of spiritual contamination he has brought upon himself. There are different degrees of such spiritual contamination, of course, and the punishment will fit the seriousness of the transgression
