The Levites were chosen by God to work in the Tabernacle (later on in the Temple) replacing the original law that every first born of each family should be devoted to serve God. In our Torah portion we read: “For they are wholly given over to Me from among the children of Israel; instead of those that open the womb all the firstborn of Israel I have taken them for Myself” (Num. 8:16) The Hebrew for wholly given is Netunim Netunim. Rashi, quoting a Midrash, says that the repetition of the word Netunim (given over for) means that the Levites were given over for two different works: on the one hand singing and on the other hand carrying all the vessels and the equipment of the tabernacle from one place to the other.
The Levites were held in high esteem by the Israelite society and by God himself. To be a Levi was to have a respected and honored position in the times of the Bible. They sang to God and to the people, beautifying the service, but they were also responsible for carrying, schlepping from one place to the other all the furniture and the structure of the Tabernacle. They were at the same time the Cantor and the janitor. A true leader, a person wholly devoted to God, to a goal, to his company or to his ideals should be willing to always do both the most elevated task and the most mundane task. With the same passion he employs in singing to God, he should be dismantling the bars of the tabernacle. The big things and the small things, what is shown in the scene and what is going on behind the scene, are both holy work. A true leader should never say “this work is not for me” or “this is too low for my status”. A true leader knows that every task is important and is holy and if he needs to pull up his sleeves to get the job done then he should do it.
