Genesis 23:2

בקרית ארבע literally, the city of the Four, and it was so called because of the four giants who lived there: Ahiman, Sheshai, Talmai and their father (Numbers 13:22). Another explanation is that it was so called because of the four couples who were buried there, man and wife — Adam and Eve, Abraham and Sarah, Isaac and Rebecca, Jacob and Leah (Genesis Rabbah 58:4). ויבא אברהם AND ABRAHAM CAME from Beer-Sheba לספוד לשרה ולבכותה TO BEWAIL SARAH AND TO WEEP FOR HER — The narrative of the death of Sarah follows immediately on that of the Binding of Isaac, because through the announcement of the Binding — that her son had been made ready for sacrifice and had almost been sacrificed — she received a great shock (literally, her soul flew from her) and she died (Pirkei DeRabbi Eliezer 32).

וַתָּ֣מׇת שָׂרָ֗ה בְּקִרְיַ֥ת אַרְבַּ֛ע הִ֥וא חֶבְר֖וֹן בְּאֶ֣רֶץ כְּנָ֑עַן וַיָּבֹא֙ אַבְרָהָ֔ם לִסְפֹּ֥ד לְשָׂרָ֖ה וְלִבְכֹּתָֽהּ׃

And Sara died in Qiryat-arba; that is Ḥevron, in the land of Kena῾an: and Avraham came to mourn for Sara, and to weep for her.
