Have you ever read through the detailed description of how the tabernacle was to be constructed?

One interesting piece found in Genesis 38:24 is the amount of gold used. We read here that "The total amount of the gold from the wave offering used for all the work on the sanctuary was 29 talents and 730 shekels, according to the sanctuary shekel" That is roughly 2,193 pounds of gold. To put that into perspective, given the price of gold today (1,556/oz) that is over $54.6 Million dollars! This doesn't include the silver, linen, bronze and expensive linen items.

Wonder why God required so much be invested into the Tabernacle?
