In this week's Torah portion, Vayechi, we witness a conversation between the aged patriarch Jacob and his son, Joseph. Joseph brought his two sons to Jacob for his blessing. He placed Menashe, the first born, near Jacob's right hand and Efraim, the younger of the two, near Jacob's left hand. However, when Jacob blessed the youngsters, he crossed his hands over and placed his right hand on Efraim's head and his left on Menashe's head.
Joseph explained to Jacob, "It is not so, my father." Moving Jacob's hands, he continued, "for this is the first-born."
"I know, my son, I know," was Jacob's reply. "Also he [Menashe] will become a people. He, too, will be great. But his younger brother will be greater than him."
According to our Sages, neither Jacob nor Joseph made a mistake. Rather, their priorities were different.
Menashe and Efraim symbolize two distinct aspects of a Jew's G-dly service. Joseph believed that the G-dly service represented by Menashe was more advantageous, whereas Jacob felt that Efraim's was higher.
Joseph named his oldest son Menashe - "For G-d has caused me to forget ("nashani") all of my toil and all my father's house." This name intimates Joseph's anguish over being distanced from his father's home and his native lifestyle. His younger son, he called Efraim - "For G-d has caused me to be fruitful ("hifrani") in the land of my affliction." Here, Joseph thanks G-d for the benefits that he reaped specifically because he was living in exile.
When Joseph brought his sons for his father's blessing, his feelings of sorrow over being separated from his family ruled. The spiritual service this parallels is the desire to cleave to G-d, even in exile. Jacob, however, viewed the exile differently, represented by the name Efraim. He saw that there is an "advantage" of exile; in exile, one changes darkness into light. And the light which follows darkness is much brighter, much more noticeable.
The paths of Joseph and Jacob should both be manifested in our lives. We must realize that we are far away from our "father's house"; we are still in exile and the final Redemption has not yet come. Just as important, or possibly more important, is to realize that we can actually light up the darkness of exile. This comes about through studying Torah and observing the commandments.
When a Jew finds himself in a situation or surroundings which are uncomfortable, he must not only be troubled by it and think of the day when he can escape. Rather, he should work to his utmost ability to change that which is bad to good, the dark to light, for this is the entire purpose of being in exile.
