Why dont we see any concern by Avrohum Avinu A”H over Hager at either of her 2 expulsions from his home?.
He was concerned about Yishmael.
See Pirush Hamishnayos L’ambam Avos 5:19 Those who dont have it handy go to http://www.hebrewbooks.org/pdfpager.aspx?req=42469&st=&pgnum=21&hilite=
It still is hard to understand. Given that ???”? suppreseed his gahmiyos but why wasnt he concerned over Hager about who ??”? say ??? ????? ????? ????? ?????? and was concerned over Yishmael who OTD ed?
2) Why did Hashem tell him not be concernd over Hager when he wasnt?
