Why Was Yaakov Punished for Hiding Dinah from Esav?

The shiur addresses a fundamental contradiction between two episodes involving keeping daughters away from Esav. Chazal relate that Yaakov hid Dinah in a box when meeting Esav, and was punished for this—Dinah later fell into the hands of Shechem as a consequence. Yet in the previous parsha, Leah is praised as having tremendous virtue (maalah) for crying until her eyes became unattractive, all to avoid marrying Esav. The Torah (תורה) itself presents Leah's appearance negatively, yet this is considered praiseworthy because it helped her escape Esav. How can the same action—keeping a daughter away from Esav—be both a virtue and a sin? Rabbi Zweig offers a fundamental distinction: the difference lies in who bears responsibility and who can handle the confrontation. Regarding Leah, the protagonist is a woman facing Esav directly. A woman cannot handle Esav—he would dominate, manipulate, and ultimately destroy her spiritually. She would become like him; he would never become like her. Therefore, keeping away from Esav is not just acceptable but praiseworthy when a woman would face him alone. Lavan and Esav had an alliance, and without Leah's intervention, she would have been swallowed up entirely. It was not even conceivable for her to marry him and survive spiritually intact.
