Vayeira

Why does Avraham(18,3-Rashi-2nd pshat) ask Hashem not to leave only after(18,2)he ran to greet the guests and bowed down to them? Avraham should have to ask Hashem first not to leave and only afterwards run to greet the guests!

Vayeira

Why does Hashem need to send a Malach to tell Avraham that Sara wil have a son?Hashem just told him 3 days earlier in17,16+19! It can't either be so Sara finds out because then the logical thing to do would be to have Avraham pass on the message to Sara, and then she probably would have believed him as he is a Navi Muchzak(Established)!

Vayeira

How could people say that (21,7-Rashi) Sara never gave birth?She must have looked very clearly pregnant for many months already!

Vayeira

(18,2)Why'd the Malach destroying Sedom(Gavriel)bother coming to Avraham?His mission has nothing to do with visiting Avraham!

Vayeira

What's Rashi mean(18,11)Sara stopped having Dam Nida?Sara just(18,8Rashi)became a Nida(&made the bread Tamei)!

Avram tells Sarai12,13" please say you are my sister so they'll be good to me(Rashi-give me presents)for your sake and let me live because of you"Why is the first thing Avram tells her"I'll get presents"?Forget that,the main thing is"I'm gonna live"!

Tanchuma-Vayeira3-Before Avraham got a Bris he asked three friends if he should and two of them said no. Why'd Avraham ask them what to do? If Hashem said he must get a Bris,he must! Also,what's the point of asking them if didn't follow their consensus anyway?
