1) Ch. 23, v. 2: "Vatomos Soroh b'Kiryas Arba hee Chevron" – And Soroh died in Kiryas Arba it is Chevron – Wasn't Soroh in B'eir Sheva?
2) Ch. 23, v. 4: "Geir v'soshov" – A sojourner and an inhabitant – Rashi comments that Avrohom said that if they would not cooperate to sell him the burial area he requested, he would rightfully take it by force, as he was a “toshov.” This seems contrary to the words of Rashi on 13:7, that as long as the Canaanites ruled the land it was rightfully theirs.
3) Ch. 23, v. 9: "M'oras hamachpeiloh" – The double cave – What was double about this cave?
4) Ch. 23, v. 10: "L'chole bo’ei shaar iro" – To all who COME to the gate of his city – Compare this with "l'chol YOTZEI shaar iro" (Breishis 34:24) by Sh'chem.
5) Ch. 24, v. 57: "V'nishaloh es pihoh" – And we will ask her opinion – In verse 51 we find, "Hi'nei Rivkoh l'fo'necho kach vo'leich," clearly stating that it was a done deal, so why do her mother and brother suggest that she be asked?
