וָאֹמַ֣ר לַמֶּ֔לֶךְ אִם־עַל־הַמֶּ֣לֶךְ ט֔וֹב וְאִם־יִיטַ֥ב עַבְדְּךָ֖ לְפָנֶ֑יךָ אֲשֶׁ֧ר תִּשְׁלָחֵ֣נִי אֶל־יְהוּדָ֗ה אֶל־עִ֛יר קִבְר֥וֹת אֲבֹתַ֖י וְאֶבְנֶֽנָּה׃
et je dis au roi: "Si tel est le bon plaisir du roi et si ton serviteur possède ta bienveillance, envoie-moi en Judée, dans la ville où sont les tombeaux de mes pères, pour que je la rebâtisse."
Radak
אשר גר שם אברהם ויצחק, this is mentioned seeing that now Yaakov also sojourned there. It teaches that it is appropriate for a person to be buried in the town where his ancestors had lived as it is a sign of honour for his ancestors who were also buried there. Nechemyah speaks repeatedly of “the city where my fathers have been buried;” he attributed the significance to the fact that several generations of his ancestors had been buried in the same place. (Nechemyah 2,3 and 2,5)
