Portion Toldot
"The voice is Jacob's voice, and hands are the hands of Esau." (27, 22)
Our sages of blessed memory said: "When the voice sounds of Jacob - no hands of Esau." In other words: when Jacob's voice, the voice of the Torah, there was not Esau's hands control. However, if the voice of Torah weakened the hands of Esau may prevail. The second half of the proverb has been fulfilled with the destruction of Jerusalem. And Jeremiah said: "What was lost land? Because they leaving the Torah."
Even in our time, after the destruction, it is necessary to emphasize that the existence of Jerusalem depends on the study of Torah. Yes, even you cannot, of course, prevent the destruction in the past, but After all we have to cancel the cause of the destruction, and also hurry to accelerate the building of the redesign of Jerusalem and the Temple.
Moreover, our rabbis of blessed memory said: "Every generation that the Temple was not built in his time - consider him as if his time was destroyed." Accordingly, there to see the destruction as happened in the past, one-time phenomenons, whose consequences continue to this day, but have to feel as if the destruction is happening now. At this moment, as it was, destroyed the Temple. If yes, of course it is our duty we cannot just cancel the cause of the destruction that happened once, but also to stop and prevent this destruction. By studying the Torah and bring an end destruction - rebuilding of Jerusalem.
