After all the components of the Tabernacle were fashioned, the people brought them to Moses. Moses inspected their work and found that everything had been prepared exactly according to the instructions that he received from G‑d. He then blessed the Jewish people, praying that G‑d rest His presence on their handiwork, as He had promised.
The Need for a Moses
וַיָּבִיאוּ אֶת הַמִּשְׁכָּן אֶל מֹשֶׁה וגו': (שמות לט:לג)
[The Jewish people] brought the Tabernacle to Moses. Exodus 39:33

The people knew that Moses had to erect the Tabernacle, even though they had done all the work of constructing and preparing its components themselves.

The same applies to the inner, spiritual Tabernacle that we are to construct within ourselves. We must do all we can on our own to form and prepare all its parts, but after that we must enlist the aid of our “Moses” – the mentor who teaches us the Torah and shows us how to live according to it – whose task it is to connect us with G‑d. Then we can be assured that all the pieces of our inner Tabernacle will unite seamlessly to perform their function in the fullest way.1
