Some of us who have made Aliyah to Israel did it on blind faith. Some succeeded some failed. Some made pilot trips and secured employment first and others went from job to job. Avram did not have an absorption center to rest in while settling in. He had to pack food, a tent and something for business.
This is a great Pshat that Avram is blessed and completely leaves his father’s house at the age of 75. However, both Rabbi Mimran Shlita and I forgot how we got to the age of 70 when the Bris between the pieces occurred. For this we go back to what I wrote in 5774 (2013).
The earliest time that I can derive is that it is no earlier than 25 years prior to the birth of Yitzchak or 425 years before the Exodus. So I am 5 years in the best case short of what is written in Shemos 12:40 on 430 years. In the 1000 plus years after what Rashi wrote, I am sure that I am not the only Jew with this question and there must be an answer.
There was also another problem that would make Avram 73 or 74 minimum at the time of the Bris Between the Pieces: The splitting of the language was in 1996 when Avram was 48. Artscroll and others then write about the various kings 14:4 Twelve years they served Chedorlaomer, and in the thirteenth year they rebelled. 5 And in the fourteenth year came Chedorlaomer and the kings that were with him, and smote the Rephaim in Ashteroth-karnaim, and the Zuzim in Ham, and the Emim in Shaveh-kiriathaim,
The account in the Artscroll adds 25 perhaps one can say in the 26th year. So the division of languages occurred when Avram was 48 plus 25 years of conquest and rebellion is 73 years old. I will get back to his after the explanation of the age of 70 from Rabbi Mimran and then Rav Schatz.
RABBI SHLOMO MIMRAN Shlita found the answer to my question. The 430 years written in Shemos on the spot Sifsei Chachamim writes that the Bris occurs when Avram was 70 years old based on Seder Olam. On Chapter 15 of our Parsha Tosfos Dalet of our Pasha brings down Seder Olam. Avram was 48 when the Tower of Bavel occurred, 58 when Noach passed away and 70 at the Bris between the pieces. Since it is written “After” and not “Afterwards” this occurred immediately after the war of the 4 kings. What appears to have happened is that Lot had left Haran to live the fertile and rich Sodom and the news of his capture reached Avram who then fought the war. This does not necessarily coexist with the Pshat what is written but the tradition of Seder Olam is very strong. It also gives backing to my theory that there was a previous trip to Canaan. One must remember another rule regarding the Torah. There is no early and no late in Torah. The commentary Shor Ha Bechor also holds by 70 years as the age Avraham was at the time of the war and sacrifices afterwards.
Rav Schatz has either Hammurabi retiring or be disposed and moving to Haran at the age of 70 perhaps being conquered by Nimrod aka Chedorlaomer. Lot perhaps was sent as Judge to Sodom by Hammurabi and is now captured and then Avram rescues him and brings him to Haran for 5 years.
Regarding the Artscroll 25 years my theoretical answer is as follows and it is speculation: However, Seder Olam says differently and it is an ancient book based on tradition either from Avraham or Moshe from Sinai. So I have to agree that the Bris occurred at the age of 70. This still leaves me with what about the forming of the nations and the languages?
For this I have to go back to Parsha Noach. 9:1 And God blessed Noah and his sons, and said unto them: 'Be fruitful and multiply, and replenish the earth. We therefore see a reason to spread mankind out over various lands. But if they were spread apart so far how did they get together to build the Migdal Bavel? The answer can be found in Malachim aka Kings 1:5:26 And the LORD gave Solomon wisdom, as He promised him; and there was peace between Hiram and Solomon; and they two made a league together. 27 And King Solomon raised a levy out of all Israel; and the levy was thirty thousand men. 28 And he sent them to Lebanon, ten thousand a month by courses: a month they were in Lebanon, and two months at home; and Adoniram was over the levy. 29 And Solomon had threescore and ten thousand that bore burdens, and fourscore thousand that were hewers in the mountains; 30 besides Solomon's chief officers that were over the work, three thousand and three hundred, who bore rule over the people that wrought in the work. Therefore just as Melech Shlomo would take people for a month’s duty and then return those to their households to work the land so I assume the work on Migdal Bavel went. For had they had compassion on people who fell or died during the building as they had on the bricks that broke even if they made war with HASHEM or thought they could, they would not have been punished. However, their cruelty to their fellow man sealed their fate.
Once you had 70 languages plus the original Hebrew you could no longer rule efficiently and therefore some of the subservient kings rebelled against Nimrod and his taxes that they did not understand anymore.
5 And Abram took Sarai his wife, and Lot his brother’s son, and all their substance that they had gathered, and the souls that they had gotten in Haran; and they went forth to go into the land of Canaan; and into the land of Canaan they came. 6 And Abram passed through the land unto the place of Shechem, unto the terebinth of Moreh. And the Canaanite was then in the land. 7 And the LORD appeared unto Abram, and said: ‘Unto thy seed will I give this land’; and he built there an altar unto the LORD, who appeared unto him.
In my Sukkos-Beresheis Drasha I wrote that Gog and Magog most likely would come via Schem. There is some logic that the first advancement in the land and the promise to Avram is reiterated at Schem. The fact that Avram made the area holy first is the contra to Magog.
8 And he removed from thence unto the mountain on the east of Beth-el, and pitched his tent, having Beth-el on the west, and Ai on the east; and he built there an altar unto the LORD, and called upon the name of the LORD. 9 And Abram journeyed, going on still toward the South. 10 And there was a famine in the land; and Abram went down into Egypt to sojourn there; for the famine was sore in the land. 11 And it came to pass, when he was come near to enter into Egypt, that he said unto Sarai his wife: ‘Behold now, I know that thou art a fair woman to look upon.
According to Rashi up until this point Avram did not mention to Sarai anything about her looks. Now, however, he does mention something to get her to cover-up, Can you imagine a generation without make-up or at best minimum cosmetics.
12 And it will come to pass, when the Egyptians shall see you that they will say: This is his wife; and they will kill me, but thee they will keep alive. 13 Say, I pray thee, thou art my sister; that it may be well with me for thy sake, and that my soul may live because of thee.’ 14 And it came to pass, that, when Abram was come into Egypt, the Egyptians beheld the woman that she was very fair. 15 And the princes of Pharaoh saw her, and praised her to Pharaoh; and the woman was taken into Pharaoh’s house.
Mitzrayim was from Cush and dark skinned. Sarai was most likely a brunette but with a much lighter complexion and therefore more attractive to the Egyptians. Remember according to the Medrash there was no external aging until Avraham prayed so that he could be distinguished from his son Yitzchak. So even at 65 or to see Rashi’s comment upon her death that she was seven and twenty and one hundred years that at the age of 100 she looked like a 20 year old.
