Vayakhel - Pekudei contains the precise dimensions of the Mishkan, but these already appeared in Teruma and Tetzaveh. Why did "Moshe followed the instructions" not suffice? We try to understand the secrets behind this "list - repetition" phenomenon in Vayakhel - Pekudei. 

We relate to the question of the detailed language and repetition of our parsha by looking at the wider context of the latter part of the Book of Shemot.
Is this repetition part of the emphasis on the possibility of Israel's atonement for the Sin of the Golden Calf? Ultimately, the structure of the parasha and Sefer Shemot is such that it ends off with the message that God has come back to dwell within the midst of Israel, as the Mishkan is filled with a Divine cloud.
