how beautiful is the Torah Kedumah, how beautiful and how sensitive it says goodbye to two main charactars, to Avraham and Sarah. A few words the Torah needs for each of them. For Sarah it says, וַיִּנָּחֵם יִצְחָק, אַחֲרֵי אִמּוֹ, "and Yitzchak was consoled ,after his mother." And a little later, בְּעוֹדֶנּוּ חַי, "while he was still alive," for Avraham.
