What are "Mechorosayich"?
Rashi: This is like Megurosayich (the places where you dwelled 1 ).
Rashi citing Menachem: It is an expression of offspring, like "Klei Chamas Mechoroseihem" (Bereishis 49:5), "Ish me'Es Makaro" (Melachim II, 12:6), "Levad mi'Mekarav" (Devarim 18:8).
Rashi (9): This entire matter is a Mashal. Yonason explained it all; one should not add to the Targum. Mechorosayich is your [initial] residence.
Why does it say "me'Eretz ha'Kena'ani"?
Rashi (9, citing Targum Yonasan): From your [initial] residence and birthplace in Eretz Kena'an, I revealed Myself to you father Avraham in Bris Bein ha'Besarim, and informed him that you will descend to Egypt, and with a raised arm I will redeem you..
Radak: Your deeds resemble the culture of Eretz Kena'an, as if you were born there and dwelled there.
Malbim: The verse depicts that [Yisrael] in Egypt were as if this [abandoned] girl was from a foreign nation, and her ancestors dwelled in Eretz Kena'an.
Why does it say "Avich ha'Emori v'Imech Chitis"?
Rashi: Avraham and Sarah received their grandeur from the Emori, and Bnei Ches gave to Sarah a burial place.
Rashi (9, citing Targum Yonasan): In the merit of your fathers I will cut off the Emori and destroy the Chitis.
Radak: It is as if your father is an Emori and your mother a Chitis, for you did like their deeds.
Malbim: The girl's parents were from different nations ? her father was Emori, and her mother was from Bnos Ches. Since they were from different nations, they were not concerned for their child. The Emoriyim were worse than other nations. Bnos Ches had worse Midos than women of Emori ? "Katzti b'Chayai Mipnei Bnos Ches 1 " (Bereishis 27:46).
Malbim (the Nimshal): Yisrael in Egypt] were not yet clarified to be a special nation. They clung to the abominations of their parents, from whom they were born. They learned Darchei ha'Emori to the point that Emori was their father and teacher. The nature of the land in which they were born (Eretz Ches) was in them; Chevron, where Avraham and Yitzchak lived, was of Bnei Ches. The verse depicts that the nation is the father of the individuals, for they learn the ways of the nation from which they left. The land is called the mother, for from it [the child] suckles its food; his nature resembles the nature of the land, its Peros and air.
What is the source that it was due to their Midos, and not due to their idolatry! Perhaps Rivkah was used to seeing idolatry in her father's house, so it would not make her loathe life. However, perhaps also there it distressed her, therefore she decided to go with Eliezer even if they object (Rashi Bereishis 24:58)! Or, it distressed her more after not seeing it for 60 years, and seeing that her own son allows his wives to do it! Or, they served more than her family did ? Nochrim in Chutz la'Aretz are not real idolaters ? it is just a tradition from their ancestors (Chulin 13b). If all the Kena'ani nations served idolatry equally, perhaps Rivkah specified Bnos Ches, for they had the worst Midos - but what is the source for this? (PF)
