The following dvar Torah was sent to me in an email. I looked it up in Tiferes Yonasan to confirm that it is authentic. Sure enough, this vort can be found in Tiferes Yonasan Breishis 29:9:
From Reb Yonasan Eybushitz Z"L.
The parsha says that Rochel was the shepherd of her father's sheep. The gemara (or medrash) says that the reason for this was because Lavan did not have any sons. So why wasn't Leah also a shepherd? After all, she was older than Rochel.
Reb Yonasan says that Lavan was training Leah to be an "Akeres Habayis" - a housewife that will take care of the home.
So why was Lavan training Leah for one job and Rochel for a different one?
Lavan's cheshben was as follows: He knew that Leah was destined to marry Eisav, while Rochel was supposed to marry Yaakov. Eisav was an "Ish Tzayid" - a hunter who made a living. Therefore, Leah was being trained to be a housewife.
Yaakov, however, was an "Ish Tam" - who sat and learned all day. A kollel yungerman. Therefore, his wife was being trained as a shepherd so she can make a Parnassah and support her family!
Here is yet another nail in the coffins of those who maintain that there was no Chareidi ideology or "Kollel" concept before the 19th century (the Enlightenment). Rav Yonasan Eibeshitz, ZT"L, passed away in 1764. And the events of this pasuk occurred in 2185 (1573 BC).
