Success in business is defined by growing capital, not by merely preserving it. If you invest $1,000 in a venture and get $1,000 back a year later - that's a business failure. In this week's parsha we learn of Yaakov's blessing to his two grandchildren Menashe and Ephraim. When Yosef learned of his father's failing health he journeyed to Goshen with his sons to receive a final blessing. Following protocol, Yosef placed his oldest son Menashe to Yaakov's right and Ephraim to his left, with the intention that when Yaakov (who was blind of old age) would lift his hands in blessing, the right hand would be placed on the head of the first born son. To Yosef's disbelief, Yaakov lifted his right hand and intentionally placed it on Ephraim's head and his left hand on Menashe's head. “Father, not so,” he protested. “Menashe is the eldest, place your right hand on his head.” Yaakov responded “I know my son. Menashe's descendants will be great too, but Ephraim's descendants will be even greater.” As is the case with every episode in Torah, this story provides us with a timeless lesson. Their exchange represents a fundamental debate in Jewish life that resonates until today. Yosef fathered his two sons in the midst of a painful separation from his family, living in the most spiritually challenging circumstances imaginable. He expressed the two conflicting drives animating his life by naming his sons Menashe and Ephraim. Menashe represents the fact that “G-d has caused me to forget (nashani) my past hardships, but this success can cause me to forget all that I have held dear in my father’s household.” Yosef understood that his stratospheric political rise and financial prosperity carried with it the grave danger of assimilation. By naming his child for the new challenge he faced, he ensured that he always remember and remain true to his heritage. Ephraim represents the fact that “G-d has made me fruitful (hifrani) in the land of my suffering.” Despite his unbearable pain, Yosef succeeded in transforming personal tragedy into an opportunity to bring divine awareness to Egyptian society. In the endless debate of how to ensure Jewish continuity there are those who opt to isolate themselves, to protect the spiritual integrity of those who are already committed to a Torah lifestyle, versus those who insist on spreading the word to the entire world, even at the risk of exposure to spiritual challenges. Yosef’s priority was to remember his roots and never lose touch with his spiritual sensitivity, and named his eldest Menashe. Yaakov, as the leader and prophet of the generation, placed a premium on Yosef’s success in his mission to bring divine morals and ethics to a place of darkness and depravity, and placed his right hand on Ephraim. Although our main purpose is to bring the light of Judaism to every corner of the earth, at the same time it is crucial to immunize ourselves to the challenges that abound outside the cocoon of spiritual bliss. We must strike the winning balance.
