“These are the accountings of the Tabernacle as ordered by Moses.”
~ Exodus 38:21

As a Divine document, it’s a foundation of Judaism that the Torah doesn’t waste words.

Yet after expending thousands of words in many chapters describing the building of the Tabernacle and all its implements, the Torah now repeats every aspect again, in detail, to show exactly how much of each material was donated.

Why? And how come it was Moses who ordered this?

Because money has the uncanny ability to blind, anyone who manages it must show accountability. Even Moses.
