The Architecture of Holiness By Rabbi Jonathan Sacks

From here to the end of the book of Exodus the Torah describes, in painstaking detail and great length, the construction of the Mishkan, the first collective house of worship of the Jewish people. Precise instructions are given for each item – the tabernacle itself, the frames and drapes, and the various objects it contained – including their dimensions. So for example we read: “Make the tabernacle with ten curtains of finely twisted linen and blue, purple and scarlet yarn, with cherubim woven into them by a skilled worker. All the curtains are to be the same size—twenty-eight cubits long and four cubits wide ... Make curtains of goat hair for the tent over the tabernacle—eleven altogether. All eleven curtains are to be the same size—thirty cubits long and four cubits wide ... Make upright frames of acacia wood for the tabernacle. Each frame is to be ten cubits long and a cubit and a half wide...”1 And so on Why do we need to know how big the tabernacle was?
