Vayishlach 5775

The story of Dina's kidnapping is explained by the Ramban. The 11 brothers had agreed to join and intermarry with the people of Shechem on condition that the city's men get circumcised. The brothers assumed that the city would refuse and give Dina back; but if they did follow through, the sons would take back Dina on the third day (when everyone was recovering). However, Shimon and Levi wanted full revenge and killed the entire city. Yaakov cursed them because the city of Shechem had put trust in the brothers. Yaakov saw it as an opportunity for the city to do teshuvah and follow in the ways of Hashem. Shimon and Levi's actions ruined that idea and betrayed the city.
