Parshat Vayeshev relates a seemingly disturbing series of events. After telling us that Yosef snitched on his brothers, it says that Yaakov loved Yosef more than all the other brothers and that's why he made him a striped shirt. Then it says of the brothers could no longer tolerate Yosef, and didn't believe his dreams of them bowing to him. First, why did Yaakov love one son more than the others? Second, why couldn't the brothers tolerate Yosef only after his father made him the striped shirt? Lastly, why did Yosef insist on telling his brothers his dreams, when he must have sensed that they didn't want to hear them?

Rav Kaminetsky explains that Yaakov had taught Yosef all that he'd learned in the Yeshiva (school) of Shem and Eiver where he studied, and where Yitzchok AND Avraham studied as well. The main strength of that school was that they taught Torah that could survive in negative environments. Avraham used it to deal with the rest of the world, Yitzchok used it to deal with Yishmael, and Yaakov used it to deal with Lavan and Esav. Now Yaakov was teaching it to Yosef, and the brothers were worried. Were they as bad as Esav or Lavan? Why would Yaakov have to teach Yosef that Torah? Little did they know that Yosef would need it to deal with Egypt, and all the trials he would face there. Yaakov loved Yosef more because he learned more, and WANTED the other brothers to be jealous (that's why he made him the shirt), so that they'd want to learn it too! But instead they became jealous for the wrong reasons. It was THEN that Yosef tried to tell them that they shouldn't be jealous, because he had to learn for his OWN sake, because he'd have to be a leader in a foreign land (as the dreams with stocks suggested, since there were no stalks where they lived). But the brothers had let themselves be blinded by hate, and couldn't see the truth, as obvious as it may have been.
