In the City of Lubavitch they used to announce: “VeYaakov Holach Ledarko” on Moitzei Simchas Torah. In 770, the Rebbe would sometimes call it out by himself, or ask the Gabay to call it out, at the end of Shabbos Breishis, as we are going into the first full work week after Tishrei.
The explanation of this quote, taken from a pasuk*, is: During the month of Tishrei, we were busy focusing on Hashem, davening, with our minds, hearts and speech, then, with action – mitzvos: building, and eating in, the Sukkah, lulav and esrog, and dancing, etc.
We came from such a spiritual month, spending so much time with Hashem. Now Yaakov – the Jewish nation – is going out to work, ledarko – each one in his field. We call out to them: Remember: who is going? “Yaakov” the chosen of our forefathers. Ledarko – to his way, as in B’chal derachecha do’eyhu – know Hashem in all your ways.
The month of Tishrei we were busy with Avodas Hashem. Now, one may think, we are going back to work, we are busy with ourselves. No! Our work during the year in a way might be more important to Hashem than our spiritual Tishrei, because now our Avodah is to make a dirah betactonim – A dwelling place for Hashem in this world. Each person, in his field and with his household, doing business and conducting the home according to the Torah, is bringing Hashem into his world, thereby bringing Hashem to dwell in this world, fulfilling the reason for which Hashem created the world.
