Tzaras Ayin and the Spiritual Purpose of Galus Mitzrayim

The shiur opens with a puzzling question from Parshas Vayigash: Yehuda had already volunteered that all ten brothers become slaves when the goblet was found. When Yosef reduced this to only one slave (Binyamin), Yehuda should have been relieved. Instead, "vayigash eilav Yehuda"—he becomes confrontational. Why does getting 90% less than what he offered make him angry? Rabbi Zweig explains that Yehuda realized Yosef's intention was not to punish a thief but to use Binyamin for mishkav zachar (as evidenced by Yosef's earlier statement "asimah eini alav"—I will set my eye upon him). This realization—that Yosef was acting with tzaras ayin, not respecting Binyamin's basic dignity and gender—is what triggered Yehuda's fury and his threat that Yosef would be struck with tzaraas, the Divine punishment for tzaras ayin. The core insight of the shiur is a radical reinterpretation of Pharaoh's dreams. The traditional understanding is that seven fat cows represent agricultural abundance and seven emaciated cows represent famine. But Rashi (רש"י) explains that the seven good cows represent years when "brios roim zeh es zeh b'ayin yafah"—people looked at each other with a good eye, without begrudging what others had. The cows are not symbols of meat and grain; they represent the people living during those years. Conversely, the seven thin cows represent people consumed by tzaras ayin—even when they "ate" the fat cows (consumed abundance), they remained unsatisfied and resentful. The definition of plenty, therefore, is not about quantities of food but about a state of satisfaction where one does not begrudge others their blessings. Famine is the spiritual-physical state where tzaras ayin reigns.
