P. 387
Rashi leaves the question of why the Torah says that Rivka was the mother
of Yaakov and Eisav hanging, saying that it requires further examination.
Parents naturally love their children. Avraham had compassion on
Yishmael, and so Rivka should also have had a maternal instinct to care
for Eisav. Because Eisav was antagonistic to Hashem and defiantly
wicked, she overcame that feeling and disdained him.
