יַ֣עַן אֲ֠מָרְךָ אֶת־שְׁנֵ֨י הַגּוֹיִ֜ם וְאֶת־שְׁתֵּ֧י הָאֲרָצ֛וֹת לִ֥י תִהְיֶ֖ינָה וִֽירַשְׁנ֑וּהָ וַֽיהוָ֖ה שָׁ֥ם הָיָֽה׃
Rashi on Ezekiel
The two nations Israel and Judah. The Midrash Aggadah of Rabbi Tanchuma (source unknown) explains it regarding [the incident in] which Esau went to Ishmael to become his son in law in order to persuade him to contest Isaac concerning the inheritance of Abraham, and [in order that] Ishmael would kill Isaac, and [he thought] “I will be the avenger of blood and kill Ishmael.” This is the meaning of (Gen. 27:41): “Let the days of mourning for my father draw near.” And I will inherit both Isaac and Ishmael.
