פירוש על יחזקאל 35:10

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.

and the Lord was there He knows your thoughts.
