"And they said: Shall our sister be made into a harlot?" (Genesis 34:31)
With these words the Torah concludes the story of Dina and her stay in the house of Shechem. This is one time where we feel a very tense emotional point between Jacob and his sons (there will obviously be many more). The Torah leaves us with a very strong sense of the brothers' idealism in the face of their father's pragmatism.
When Shimon and Levi have finished their act of destruction, Jacob responds with a question: although you may have been guided by your ideals, did you not think of the practical results? Jacob fears a massive uprising against his family as a response to their act. His concern seems reasonable. Yet Shimon and Levi respond with such force that we are thrown back to the side of their ideals and uncompromising act. Jacob's pragmatic concern seems to pale in the face of the issue of family respect raised by the sons.
We do not know if Jacob responded at that moment to his sons. (We do see him rebuke them, however, in his final blessing on his deathbed.) The Torah has consciously left us with the stinging words of the brothers ringing in our ears. Why? Was Jacob really silenced? Perhaps the Torah wanted to show us the two sides of the coin and leave the question at that. Indeed, all of our acts should be guided by a passionate idealism. At the same time, however, we must be aware of the practical, pragmatic results of our actions. Was Jacob right? Were the brothers correct? The Torah has clearly chosen not to pass judgement. (The commentators, as well, are split on this issue.) This is a question that will always attack us. Our ideals must always be strong. Our sense of pragmatism must always be keen. How the two will interact is something only we can answer as we go through our lives.
