וָאֹמַ֣ר לַמֶּ֔לֶךְ אִם־עַל־הַמֶּ֣לֶךְ ט֔וֹב וְאִם־יִיטַ֥ב עַבְדְּךָ֖ לְפָנֶ֑יךָ אֲשֶׁ֧ר תִּשְׁלָחֵ֣נִי אֶל־יְהוּדָ֗ה אֶל־עִ֛יר קִבְר֥וֹת אֲבֹתַ֖י וְאֶבְנֶֽנָּה׃
Y dije al rey: Si al rey place, y si agrada tu siervo delante de ti, que me envíes á Judá, á la ciudad de los sepulcros de mis padres, y la reedificaré.
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)
