Fetal movements[1]
ויתרצצו הבנים בקרבה ותאמר אם-כן למה זה אנכי ותלך לדרש את-יקוק
The babies jostled within [Rivka]. She said: “If so, why did I pray for children?” [So] she went to seek [guidance] from Hashem[2]
When Rivka was expecting twins, Yaakov and Eisav, she had a difficult time. No, not the usual struggles of pregnancy. Our Sages tell us[3] that when Rivka would stand near shuls and study halls[4], Yaakov would try to “run”[5] out of her womb towards them. When Rivka would pass by houses of idol worship[6], Eisav would try to “run” out of her womb towards them. There are many difficulties with this Midrash. How could Yaakov and Eisav, fetuses in the womb, have a sense of good and evil? How could Yaakov be drawn to good, and Eisav drawn to evil?
