What claim did Sarah have against Avraham?
Rashi #1: That when he prayed for children, he only prayed for himself and not for her as well. 1
Rashi #2, Targum Yonasan, Seforno, Moshav Zekenim: When Hagar disgraced her, he remained silent. 2
Had you prayed also for me, perhaps now I too would already have been granted children!
Targum Yonasan adds that, she reminded him that she had left her land and father's household to accompany him to a foreign country and had given him her maidservant as a wife. And now that that maidservant had demeaned her, she expected him to defend her. And she concluded that, now that Avraham had remained silent, she relied on HaSh-m to do stand up for her, and that she would bear him children who would fill the land; consequently, there was no need for Hagar to have children.
Why does the word "u'Veinecha" have a second "Yud" (unlike other occurrences of this word)?
The Gemara says (Bava Kama 93a) that Sarah asked HaSh-m to judge between her and Avraham, and that therefore, she was punished first. But Hagar miscarried long before Sarah died!
Moshav Zekenim #1: Immediately, Sarah's apportioned years were reduced, before Hagar miscarried!
Moshav Zekenim #2: The miscarriage was not due to this judgment. Sarah did not care about it.
QUESTIONS ON RASHI
Rashi writes: "You should have prayed for both of us.... Furthermore, you are withholding your words [now]; you hear my disgrace and remain silent." Why does Rashi use the term "furthermore" (v'Od) rather than "alternatively" (Davar Acher)?
Gur Aryeh: The word "injustice" (Chamas) is used without specifying; it includes any injustice, and so both explanations are implied in the verse.
