In order to prevent the chance of someone offering a sacrifice to other deities, the Torah demands that the locale for all sacrifices that are either voluntary or mandatory be the central house of worship, the holy Temple or tabernacle prior to the permanent Temple. Also, such sacrifice must be performed by the priest, who will sprinkle the blood and burn the fat on the altar provided for that purpose. This is an "eternal statute for all your generations." (Leviticus 17,7) Even the slaughtering of the sacrificial animal outside the precincts of the Temple compound is an offence carrying the karet, penalty, (premature death at the hands of G'd) The burning of any of the remains of the animals in a place not designated for that purpose is eaually prohibited, (ibid verse 19) (1) So much for the spiritual aspect of the matter. (2) Then the Torah addresses itself to the physical aspects of the sacrifices, namely the eating of the blood of the animals that had been offered as sacrifices. Since blood represents the personality of the creature, its consumption would superimpose the animalistic personality on the person who consumes it. The result would be that that man who is always a blend of spiritual and material forces would become predominantly materialistic. His spiritual forces would lose the chance of gaining the ascendancy within him. The result would be the destruction of his personality, i.e. karet extinction. As long as Israel had been in the desert, all blood of animals to be eaten, had to be poured out on the altar as if to dedicate the animal's personality to G'd. Man must dedicate himself, -in this case his sacrifice, seeing it is his alter ego-, to the Lord. "Love the Lord your G'd with all your soul, personality." Many heroes of the Bible describe their endeavours in those terms. When David prepares for battle against Goliath, he voluntarily risks his life for the sanctification of G'ds name. Jonathan tells his father about David that "he has put his soul, his personality in his hand" in order to kill the Philistine. (Samuel I, 19,4) Yiftach expressed himself in similar terms before going into battle against the Bney Ammon. (Judges 11,30) When a person takes risks like the ones described, for a cause other than the glorification of the name of G'd, such as for the sake of personal glory and honour, he is merely making himself guilty of suicidal conduct. David refused to drink the water that had been obtained for him by three brave soldiers at the risk of their lives. (Samuel 11,23,14-17) (3) Instead, David tried to obtain atonement for the men who had mistakenly risked their nefesh, soul, life for such mundane matters, by making a drink offering to G'd of these waters. David would have considered drinking this water as not much less sinful than drinking blood. Since nefesh belongs to G'd, a Jew must not consume it. Since nefesh resides in the blood, blood must not be eaten. (5) On the one hand, blood as the carrier of nefesh, is like a vessel containing vital fluid. If the container leaks, the fluid will be lost. On the other hand, it is the fluid which enables everything to feed upon it. The body is diffused with it, nourished and sustained by it. They are inextricably interwoven, and the description by the Torah once as if blood is the primary agent, and on the other occasion as if nefesh is the prime factor, is quite apt. (4) This function of blood is also the reason that blood of animals that are not suitable for sacrifice is prohibited. Absorption of the animalistic life essence of the animal by man's body, would result in man himself becoming more animalistic, predominantly so. When G'd said to Cain "the voice of your brother's blood cries out to Me," (Genesis 4,10) He refers to the fact that the nefesh is in that blood. (6) In the case of the birds and free roaming animals, their blood being thinner, the contribution it makes to the essence of their being is somewhat smaller. Therefore, when the Torah states "for the life of the flesh is in the blood,” this is a one sided description. In that instance, the Torah does not describe the blood as being simultaneously the vessel of the animal's personality. Nevertheless, such blood is also forbidden, seeing that the blood as an agent of the life sustaining soul, carries this sustenance to all parts of the body. Without it, the animal would die.

(14) Shmot Rabbah 1 tells us that Abraham was inferior to Sarah in prophetic insights. This may have been because she realized the fact that her son was Abraham's major issue. She was not beclouded in her judgment by the love for another son, begotten while he had not yet been circumcised. Abraham scrupulously carried out Sarah's instructions re the expulsion, and did not provide Hagar and Ishmael with money or luxuries beyond their immediate needs for survival. The "voice" of the lad that G-d heard needs to be understood in the same sense as "The voice of your brother's blood calls to Me" (Genesis 4,10), meaning G-d became aware of the great pain and discomfort suffered by Ishmael. That is why the angel said to Hagar, "Why are you afraid and raise your voice?" The Lord has already heard the suffering of the lad, even though the latter did not raise his voice. "As he is there", i.e. the situation he finds himself in is enough to warrant My intervention. The angel's appearance and instructions confirm the worthiness of Hagar that we have discussed in previous chapters when she had encounters with angels. The whole problem of her seed had been that Ishmael had been conceived while his father had still been uncircumcised. (15) Avimelech and his commander-in-chief had convinced themselves that G-d was with Abraham through three outstanding events. 1) His victory over Kedorlomer; 2) The safe return of Sarah to him after two royal kidnappings, including his own; 3) The birth of Isaac at an unbelievably old age of the parents, the other having barren up to then. For these reasons they wanted to conclude a peace treaty with Abraham. Abraham was willing and capable of swearing an oath. He said "I can certainly swear," since my honesty is not in doubt. Avimelech's honesty, however, had been cast in doubt by the actions of his servants who had been hounding Abraham's well diggers. There was reason to suspect that Avimelech had connived with, or at least condoned, the actions of his servants. Abraham wanted to study Avimelech's reaction to his complaints before entering into a treaty with someone who might be untruthful, making Abraham guilty of loving the enemies of G-d. Avimelech accepted the rebuke and replied in a proper manner, namely that justice would be done in all three areas: 1) The perpetrator of the crime would be removed from his post and be disciplined. 2) The wrong itself would be corrected. 3) Someone would be appointed to supervise that the judgment would be executed. Avimelech personally excused himself in three ways: 1) He did not know who the guilty party was, therefore he had not been able to punish that person. 2) Since Abraham had not even lodged a complaint until just then, he, Avimelech, could not possibly have redressed the wrong already. 3) He himself had only heard about the complaint just then, hence he could not have appointed a royal commission of enquiry already. When Abraham realized from the explanations offered that Avimelech had no intention of disputing the ownership of the wells, he took the sheep to proceed with the oath which had been suggested, and made a covenant. The seven extra sheep are roughly the equivalent of the field on which the well was situated, and would serve as testimony that Abraham had dug the well, not merely found it and used it. Since in dealing with royalty, he did not want to insult the king by appearing to place too much emphasis on what was after all a minor transaction, he gave Avimelech generous gifts before setting aside the seven sheep. Therefore, Avimelech asked, "What are the seven sheep that you put aside?" Abraham then answered him that those were to be the symbolic evidence that he had dug the well, and that the only thing that belonged to Avimelech was the ground the well was situated on. It was common practice at that time that anyone who found water on publicly owned land could claim the water as belonging to him. The name Beer Sheva first and foremost recalls the transaction connected with the well. However, beyond that, the site should be remembered as the spot at which the fateful covenant between Abraham and Avimelech had been concluded. The name therefore had a dual significance. By planting an orchard and staying there at least another thirty-eight years, Abraham introduced G-dliness into the land of the Philistines.

And for my offspring: see Sanhedrin 4:5 - 'capital cases, his [the defendant's] blood and the blood of his offspring depend on him until the end of the world, as we find with Kayin who killed his brother, as it says: "Your brother's bloods are calling" (Bereishit 4:10); it doesn't say your brother's blood but your brother's bloods - his blood and the blood of his descendants.' And I have no comforter - Vayikra Rabbah 32:8. The gate of tears is never locked - Bava Metzia 59a.
