Another name for the Beis Hamikdash is Beis Zevul. This name is connected to the tribe of Zevulun.
The tribe of Zevulun lived on the coast of Eretz Yisroel. They would sail the sea and engage in trade, leaving the borders and holiness of Eretz Yisroel.
And yet, the name Zevulun alludes to the Beis Hamikdash, the holiest site in the world.
Chassidus teaches that Hashem created the world because He desired a Dirah Betachtonim. He placed us in a lowly, physical world that seems distant from G-dliness so that we can transform it into a dwelling place for Hashem, where His presence is openly revealed.
Like Zevulun we travel outside of the borders of holiness, to go out into the world and engage with it. But it is with purpose, to transform the “outside” into a Beis Zevul, a sanctuary for Hashem.
Zevulun would inspire their non-Jewish business clients, bringing them closer to Hashem and an admiration for the Jewish people. Many of them would visit the Beis Hamikdash and ultimately convert to Judaism.
A businessman should see themselves as a Shaliach. In their business dealings, they have a unique ability to reach those whom others may not reach and inspire them to come closer to Hashem.
