פּירוש אויף יחזקאל 16:3

your dwelling place Heb. מְכֹרֹתַיִך, like מְגוּרוֹתַיִךְ, your dwelling place [interchanging כ and ג], and Menachem (p. 110) connected the word to the idea of birth. He similarly explained (Gen. 49: 5): “weapons of violence are their birth (מְכֵרוֹתֵיהֶם)” (Deut. 18:8); “besides what he has from his birth (מִמְכָּרָיו)” (II Kings 12:6); “each one from his kinsman (מַכָּרוֹ).” They all mean birth.

your father, etc., and your mother Abraham and Sarah took their greatness from there, and the children of Heth gave her a grave.
