Too many details… There are many places where the Torah leaves out a lot of the background story and allows the Talmud and the Middrash to fill in the blanks. Tefillan are a great example. All the Torah tells us is that we should wear them. The oral tradition tells us what they are. In Terumah, it seems to give a lot of details that aren’t so inspiring or interesting. If I would have been on the Torah writing committee, I would have probably opted to spend more time with Abraham, Isaac & Jacob and less time on the exact details of the Tabernacle.
The parsha give us a plethora of details about the construction of the following the Ark, Table, Menorah & Tabernacle. This might have been very important for them to know how to build, but what relevance does it have to us? Let’s give a brief overview in no particular order…
1. Aron (Ark) as in "Raiders of the Lost…" This is where the 10 commandments and the Torah were kept.
2. Shulchan (Table). This is wear the showbreads were placed.
3. Menorah (Menorah?) The Menorah is the Menorah. There is a difference between the Menorah in the Temple and the one we use on Chanuhah. The Menorah in the Temple had 6 branches plus the Shamash making a total of 7 where the ones we use today have 8 branches plus the Shamash making a total of 9.
4. Mizbe'ach (Alter) The Alter is the place where the Kohanim (Preists) offered sacrifices.
5. Mishkan (Tabernacle). The Mishkan was the early portable version of the Beis Ha Mikdash (Holy Temple.) It was used until King Soloman built the first Temple in Jerusalem. That lasted about 400 years until it was destroyed by the Babylonians. The second Temple was built 70 or so years later by Ezra and rebuild by Herod the Great. That also lasted about 400 years until it was destroyed by the Romans in 70 CE. When the Moshiach (Messiah) comes, we will have a Third and final Temple.
