1) Ch. 32, v. 4: "Artzoh Sei'ir" To the land of Sei'ir How is it that Yaakov sent a message to Eisov who was in Sei'ir? In 36:6-8 we see that Eisov still resided in Canaan, and only left to Sei'ir a while after Yaakov's return because of their each having large flocks and limited grazing locally?
2) Ch. 32, v. 7: "Bonu el ochicho el Eisov" We have come to your brother Eisov Why doesn't the verse say that they also did Yaakov's bidding, namely to relate Yaakov's message of verses 5 and 6?
3) Ch. 32, v. 33: "Gid hanosheh" The dislocated organ Does the prohibition to consume "gid hanosheh" apply to a human "gid" as well? Targum Yonoson ben Uziel says "divira v'cheivosa," of a domesticated or undomesticated animal, seemingly excluding that of a human.
4) Ch. 33, v. 10: "Ro'isi fo'necho kirose pnei Elokim vatirzeini" I have seen your face as if viewing the face of Elokim and you have become appeased with me After many years of separation it would seem only decent that Yaakov should make strong eye contact with his brother. However, our Rabbis tell us, "Ossur l'hista'keil bifnei rosho," it is prohibited to stare into the face of a wicked person (gemara Megiloh 28a). Although there is a prohibition against "l'hista'keil bifnei rosho," this only means to not STARE at his face, but a glancing look is permitted, which is what Yaakov did.
Yaakov therefore excused himself for this by comparing looking at Eisov with having a vision of Elokim. The great sanctity does not allow one to stare at such a vision as per the gemara Yerushalmi Megiloh chapter #4, that we may not look upon the hands of Kohanim when they pronounce their priestly benediction because there is some level of "Sh'chinoh" present. Why indeed did Yaakov even bother to look at Eisov at all?
5) Ch. 34, v. 27: "Asher timu achosom" Which defiled their sister Why are all the residents of the city held responsible for Dinoh's being violated?
