Quite simply Teraach was 70 years old when he begot abram, nahor and haran. (maybe they were triplets), All three born in UR, Haran dies in Ur . Then Terach and his two remaining sons head out to Canaan; but they came as far as haran. Now Haran was named Haran by the family in memory of their son. Clearly he was murdered in Ur and thats why his father decided to leave Ur to go to Canaan, but they liked the land of Haran and settled there. Terach dies in Haran at 205. making abraham 135 years old so it contradicts the idea that abraham left when he was 75 so it means he left before his father died when his father was 145.
One interesting point is that the samaritan Torah says that that terah lived 145 years, which would make sense that abraham left exactly after the death of his father like when they left Ur after the death of haran.
And when God spoke to abraham to go to CANAAN, the first place he goes to to build an altar is SHECHEM, (mount gerizim), the place where israel was commanded to make the blessings. According to samaritans this place is also BET -el, and is the chosen place. and Jacob also worshipped god there and say angels etc. Now the story of isaac when he is to be sacrificed is a mystery, his father and his son both worshipped at bet el which is in shechhem, and to him it just says he went to ERETZ MORIAH, now it doesnt specify which mountain, just a landform, now the difference between ALON MOREH and MORIAH is only a yud, since these places were in the land of the amorites, AMORI, MOREH, MORIAH, they are all connected . JErusalem was JEBUSITE so it doesnt make sense, and also why would isaac be taken to a different place to the place abraham chose and jacob too. and joseph was burried there, and joseph whos land was blessed, has the blessing of the burning bush or the presence of god. IE THE TABERNACLE.
Conclusion - The Samaritans indeed worship at the right site, The kingdom was divided ONLY after SOlomon built a temple in jerusalem. Since the other 11 tribes worshipped at Mount gerizim, SCHEM/BEt-el, elon moreh etc etc. 11 tribes of israel and JUDAH, JUdah was cut off from the rest of Israel, and if you say God chose Judah over the other 11 tribes, i say rubbish, firstly Bot King david and Solomon were not men of God, King DAVID FOUGHT all his wars him self, without the help of the angel of God. He Sinned horribly in the eyes of god, having multiple wives and collecting much gold and murdering etc etc etc. FOr god to make an everlasting covenant with david would seem insane. More so to allow a man like King solomon TO suddenly build a temple, after they had been 400 years worshipping god just fine in the tabernacle of moses, since to god it doesnt make a difference, temple or tabernacle, as long as its kept holy. He doesnt desire GOLD and RICH BUILDING, he is HUMBLE, he dwells in a tent. Solomon we know worshipped many gods, so it would seem crazy for god to choose his seed to make an everlasting covenant.
COnclusion, as this weeks portion is the story of Judah deciding to send Joseph away to the ishmaelites and COVER -UP josephs DEATH, so maybe he will take the glory over the rest of his brothers, the same story happened in the nation of ISrael. Judah tried to cover-up the original place of the tabernacle , and take the kingship from Joseph, but Joseph was given the blessing from jacob already. It cant be taken back.
The idea of a moshiach ben Yosef and a moshiach ben david is quite funny. I would say since joseph had two dreams about ruling over his brothers, first in EGypt when there was a famine, and secondly in the end of days when the chosen place is re-established, and TRIBE of joseph made King over his brothers, especially over JUDAH, the betrayer. Amen
