ויזכור אלהים את אברהם. מַהוּ זְכִירָתוֹ שֶׁל אַבְרָהָם עַל לוֹט? נִזְכַּר שֶׁהָיָה לוֹט יוֹדֵעַ שֶׁשָּׂרָה אִשְׁתּוֹ שֶׁל אַבְרָהָם וְשָׁמַע שֶׁאָמַר אַבְרָהָם בְּמִצְרַיִם עַל שָׂרָה אֲחוֹתִי הִיא, וְלֹא גִלָּה הַדָּבָר, שֶׁהָיָה חָס עָלָיו, לְפִיכָךְ חָס הַקָּבָּ"ה עָלָיו (בראשית רבה):

ויזכר אלהים את אברהם GOD REMEMBERED ABRAHAM — What bearing has God’s remembering Abraham upon the rescue of Lot? He remembered that Lot knew that Sarah was Abraham’s wife and that when he heard that Abraham said in Egypt regarding Sarah, “She is my sister”, he did not betray him because he had sympathy with him. For this reason God had mercy upon him (Lot) (Genesis Rabbah 51:6).
