1) Ch. 12, v. 2: "V'e'es'cho l'goy godol" - Meseches Sofrim (21:9) says that the great man among the giants is Avrohom, whose eating and drinking outweighed that of 74 men. This surely needs clarification.
2) Ch. 13, v. 7,8: "Va'y'hi RIV, al noh t'hi M'RIVOH" - Why does verse 7 use the term RIV, the male form for an argument, and verse 8 use the term M'RIVOH, the female form for an argument?
3) Ch.14, v. 13: "Vayovo hapolit va'ya'geid l'Avrom HO'IVRI" - Rashi says that Avrom was called an IVRI, which comes from the root word EIVER, a side. Avrom, who recognized that there was Hashem Who created the world and to Whom we are responsible, was on one side, while those who denied the existence of Hashem stood on the other side. Since Avrohom is mentioned in the Torah so many times, why is it that in this verse, and this verse only, is he given the appellation IVRI?
4) Ch. 14, v. 18: "U'Malki Tzedek melech Sholeim" - The story of the war of kings is recounted in this chapter, beginning with 14:1 up to this verse. The story continues again from verse 21 until its end in verse 24. Why is the meeting with Malki Tzedek interposed here?
5) Ch. 14, v. 18: "Lechem vo'yoyin" - Rashi says (M.R. 43:6) that by offering Avrom bread and wine, Malki Tzedek alluded to the flour-offerings and wine libations that Avrom's descendants would sacrifice to Hashem there (in Jerusalem). Since there are numerous other items offered as sacrifices, why did he specifically allude to these items only?
