And she went to inquire of Hashem. The Midrash explains that Rivka traveled to the Academy of Shem and Ever to ask why her child was displaying both good and evil tendencies.

But when they turned thirteen years old, one set out for study halls of Torah and the other for idolatry. When they were youngsters, not enough attention was paid to their differences, they were dealt with similarly, but they should have been dealt with individually. The cornerstone of Jewish education is treating each child as an individual.
