(1) When Lot faced the people of Sodom, he had shut the door so that the angels would not overhear the negotiations and the indecencies that the Sodomites planned to perpetrate on them. Their objective was to reinforce their image as being anti-strangers, so that this kind of news would make others shun their city. Lot's argument was that the townspeople's quarrel was only with him, not with them, since it had been he who had breached the town's regulations. His guests could not have known about these regulations. He offered his daughters as expiation for his own disloyal conduct, not as substitute for the strangers. The reference "that is why the men came to my house for shelter" means they did not know that the laws of Sodom forbade visitors; they are not guilty therefore. (2) In their reply gesh hal-ah, "out of our way," the townspeople refused to accept this argument, and threatened to deal more harshly with Lot than with the strangers, since he, Lot, had dared put his own interpretation on the rights and wrongs of the case. Lot had classified the strangers as not subject to the town's jurisdiction. Therein lay his sin, in the eyes of the townspeople. The old man in Givah however, had not used his daughter and the concubine to atone for his mistakes as Lot did, thereby acknowledging the town's laws as proper and just. He had done so simply to relieve the pressure and the threat of death to himself and his guest. (3) When the angels saw that the whole town was of one mind, and that even Lot's sons-in-law considered the idea of heavenly retribution as absurd-- believing that no such retribution was called for-- they realized that G-d’s criteria, "if I see that what is happening is as bad as what I have heard, that is the end," had been met. Destruction was called for. The pressure on Lot was designed to make him pray for the survival of Tzoar, since there were an insufficient number of good people there who could have insured the town's survival. The arrival of Lot in Tzoar would augment that meager number of good people there. All this was to show Abraham that G-d had not only met the conditions Abraham's prayer had called for, but that G-d had done His best to engineer things in such a way that the right conditions would be created. (4) Because He remembered Abraham and his prayer, He sent Lot away in such a manner. For a similar reason, on the morrow, when Abraham would return to that spot, Sodom would be gone. (5) Lot's daughters thought that Tzoar had been spared only for the sake of their family, and that upon their departure, it too would be destroyed, as in fact they thought that the whole earth would be laid waste like at the time of the deluge. The entire story is told to put misdeeds perpetrated against Israel by nations who owed their entire existence to the prayer of Israel's first ancestor Abraham into perspective. At the same time, it also explains how two "pearls" in Jewish history, Ruth and Naamah, respectively, came out of those two nations and made their magnificent contribution to Jewish history by becoming ancestors of the ultimate redeemer, the Messiah, so that David as well as Rechavam both had blood from those nations flowing in their veins. (6) Concerning Abraham's migration to the South after this catastrophe, the sages in the Midrash offer a variety of insights. Some say that Abraham was afraid that the neighborhood would henceforth be shunned by travellers, thus limiting his opportunities to proselytize. Others believe that Abraham wanted to put some physical distance between himself and the bastards born to Lot by his daughters. I believe the reason is to be found in Abraham's new destiny, acquired simultaneously with his name having been changed. To become the founder of a variety of nations requires physical exposure to different societies. He had to move to areas where he was not yet well known, in order to be able to continue his life's work. Abraham's again asking Sarah to claim that she was his sister, despite his experiences in Egypt, proves that she had indeed regained a youthful appearance as a result of the angel's blessing. Her desirability once again posed a problem to both herself and Abraham, as proved by the prompt action of Avimelech seizing her. (7) If G-d did not immediately restrain Avimelech, it may have been in order to help Abraham's economic progress while in the land of the Philistines, and to demonstrate that a G-d-fearing man could enjoy great material prosperity. G-d had to communicate with Avimelech for two reasons: 1) His own personal standard of morality was superior to that of Pharaoh. 2) In the years that had elapsed since his stay in Egypt, Abraham had attained a much higher spiritual level, and as a result he qualified for more prompt Divine assistance. While in Egypt, Abraham had not yet been able to appreciate the personal intervention in his affairs that G-d would demonstrate; now however, he was well aware of that. For that reason, Pharaoh was alerted to his wrongdoing only through the plagues inflicted upon him and his household. In the case of Avimelech, however, G-d communicated with Avimelech by spelling out his complaint to him in a dream. (8) Since beney Noach, i.e. ordinary non Jews, are automatically guilty of the death penalty if they transgress those laws that apply to them-- of which adultery is one-- the Torah has to mention the fact that an adulterous relationship had not yet taken place. Therefore, G-d could confirm to Avimelech that indeed he was not yet guilty of death. Avimelech countered that since whatever he had been about to do had been the result of being misled by both Abraham and Sarah, such an act should not have been considered a crime even if he had committed it, and that therefore no question of guilt could arise. G-d replied to Avimelech that it was true that vis a vis his countrymen he had not sinned, but that He, G-d, knew that vis a vis Him a sin had been committed, since it had only been due to G-d’s interference, i.e. making him impotent, that he had not yet committed adultery. (9) He should not think, however, that since he had begun in innocence, he could now keep the lady and consider himself free from guilt as a result of Abraham and Sarah having tricked him. He would have to restore Sarah to Abraham, who, being a prophet, was aware that Sarah had not been touched due to G-d’s intervention. Abraham would pray for the king, allowing for the fact that he had not intended to commit adultery. Avimelech was warned not to become an intentional sinner at this stage. (10) Avimelech now wanted to know from Abraham why he had felt the need to go to such lengths of deception to protect himself. Abraham replied that since the fear of G-d would not act as a restraining influence on Avimelech's subjects, he had had to look for other deterrents. Being afraid that Avimelech would say now-- just as Pharaoh had done-- "You could at least have told me that she is your wife," Abraham could not very well tell him that such a revelation might not have been deterrent enough. Therefore, he mentioned that Sarah was indeed kind of a sister to him. Since it had been legal at that time to marry blood relations of such a category as Abraham and Sarah, i.e. a niece, a lie had in fact never been uttered. Avimelech had simply failed to ascertain whether there was an additional relationship that existed between Abraham and Sarah beyond their being brother and sister. Hence he had only himself to blame for the complications that had arisen. Abraham explained that it had long been his practice to describe Sarah as his sister, ever since they had started to wander and had not yet reached the site of a permanent settlement. The expression hittu, is used on numerous ocasions in the same sense as hiflig, i.e. to cause to depart (compare Genesis 21,14;37,15; Psalms 107,4). In presenting gifts to Abraham, Avimelech behaved in an appropriate manner. Inasmuch as he had contravened the principle of "What is yours is yours" by appropriating Sarah without asking Abraham whether she also happened to be his wife, he atoned now by using the "What is mine is yours" principle. (11) Also, of course, he was interested in Abraham praying for his impotence to be cured. To Sarah, he remarked reprovingly that the thousand pieces of silver he had given to Abraham as her dowry had served as an eye cover to let everyone think that she had been free to marry, and that though G-d knew well enough that she had not had marital relations, no one else would know about this. He told her to mend her ways and not again practice this kind of deception. The Torah merely reports that Sarah accepted the rebuke gracefully, and indicated her being prepared to avoid creating such a misleading impression in the future. Another meaning could be that Avimelech meant "although I have paid a thousand pieces of silver to your brother, you should not have accepted this and caused suspicion about your status amongst all the people around you." Abraham's prayer, recorded at this juncture, was the first prayer that Abraham offered that had not been triggered or prompted by someone else, but was offered completely of his own initiative. It seems, according to Bereshit Rabbah 52 that "something that had kept him tied up, had now been released." This refers to another step forward in Abraham's development toward the complete and perfect personality. By announcing beforehand that Abraham would pray, the Torah further underlined this landmark in Abraham's development. "G-d remembered Sarah as He had said," by making her pregnant. "He did for Sarah as He had said," He timed the event as promised. Sarah's exclamation means, "Let anyone who wants to mock do so, I am willing to bear it, even if G-d has made people mock me; the important thing is "He made a laughter, a joy for me." (12) The words mi millel, who would have foretold, seem an added expression of thanksgiving, such as "how wonderful he who foretold Abraham that Sarah would nurse children,” for I have indeed born a son in his old age. There are numerous examples of the use of the word mi in this sense. Compare Isaiah 49,21 "Who has born me these?" (masculine usage of the verb yalad, gave birth), or Isaiah 63,1 "Who is this that comes from Edom"? (13) The display of excessive joy at the meal celebrating the weaning of Isaac, may have caused Ishmael to become concerned lest he lose part of his heritage, and he may have mocked Sarah and her having given birth in her old age. This may have angered Sarah sufficiently to ask that both Hagar and Ishmael be expelled from the household. Associating Ishmael's behavior with his mother was meant to convey Sarah's opinion that Ishmael had acted as he did only because he was Hagar's son, not because Abraham was his father. Abraham was naturally disturbed for his son's sake, but G-d intervened by telling him to give Sarah carte blanche in the matter.

54. Al Khazari: I only know that the people of the second Temple forgot the Tōrāh, and were ignorant of the law of Succāh till they found it written. A similar thing happened with the law that 'an Ammonite shall not enter the congregation of God' (Deut. xxiii. 3). With regard to these two points it is said: 'They found written.' (Neh. viii., 4; xiii. 1). This proves that they had lost the knowledge of the law.
