Aliya Summary: The Tabernacle’s construction is capped off with the construction of the Outer Altar, the copper wash basin, the mesh curtains which surrounded the Tabernacle courtyard, and the beams and hooks which anchored them. The Torah then gives an exact accounting of the amounts of gold, silver and copper donated for the construction of the Tabernacle, as well as the vessels and building materials constructed with these supplies.
We are taught from the fact that Moshe gave a voluntary accounting of the materials he collected, that a person in the position of collecting monies for the community must conduct themselves in such a way that they will always be above suspicion. Even if the individual is completely trustworthy, they should take measures to avoid the possibility of appearing improper. The Talmud tells us that the family of Kohanim that was in charge of compounding the Ketoret (incense) did not allow its women to use perfume, lest someone suspect them of taking from the sacred ingredients of the Ketoret. Similarly, the bakers of the Lechem HaPanim did not eat fine bread, so that no one should even get an idea that they were taking the special flour of the Mikdash for their own use.
