The physical T'nufa “lifting” of the Levi'im was actually a symbol of: 'ה יֵכְרַדְבּ וֹבִּל הַּבְּגִיַּו “Lifting” your heart for the service of Hashem. We find this principle repeated again, this time in the Mishkan and the Kelim. The roof of the Mishkan had a covering made of Tachash skin; this is an animal who is happy and proud of its pretty colors. [Rashi]. Although the roof of the Mishkan was assembled from four kinds of materials, only the Tachash was visible [from a helicopter view]. And when they wrapped the Kelim of the Mishkan during travel [end of Parshas Bamidbar], all the Kelim [besides the Aron] had the Tachash skin as the outside and visible wrapping. We see the importance of: 'ה יֵכְרַדְבּ וֹבִּל הַּבְּגִיַּו.
And in the beginning of Parshas Naso, all the types of skins are mentioned only by Remez, except for the Tachash which is mentioned openly. Since the Tachash boasts about itself, the Torah gives it the most conspicuous role. When you build yourself up and appreciate yourself, then the world agrees with you and respects you as well. People who don’t respect themselves, are not respected by others either. [There are exceptions though].
The Tachash is given the most attention, even though its very existence was only temporary; unlike the Tcheiles, Argaman, Tola'as Shani, etc. which are permanent creatures [from sheep and goats]. Even if you aren’t that great, you still get rewarded for appreciating yourself. [This is similar to the Orchos Tzaddikim, who says that having Simcha Shel Mitzva gives you 1,000 times more Schar].
When You Are Happy and Act Rich with A Mitzva, You Always Come Out Ahead
So always appreciate and glorify yourself, and respect the even minimal Avodas Hashem that you do. You’ll come out ahead. When the Yidden would bring their Bikkurim, the rich people would bring them in beautiful gold and silver baskets, while the poor would bring them in cheap wicker baskets. The expensive baskets would be returned back to the rich, but the poor would lose them. This can be a Remez. When you are happy and act rich with a Mitzva, you remain happy. But when you act poor and unhappy, then you lose.
