1 Moreover thou shalt make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubims of cunning work shalt thou make them.

2 The length of one curtain shall be eight and twenty cubits, and the breadth of one curtain four cubits: and every one of the curtains shall have one measure.

3 The five curtains shall be coupled together one to another; and other five curtains shall be coupled one to another.

In later verses we will learn how the frame of the tabernacle was to be built, and that it would be covered with the curtains that are described in these verses. Each individual curtain would be a very long rectangle, 7 times as long as they were wide, which seems a symbolic ratio to me.

The construction of each curtain would be done with “fine twined linen,” meaning many separate strands of flax woven together, and they would be stitched with the pattern of a cherubim, which was to be an intricate, “cunning work.” Thus, there was to be complexity and multiplicity in this border, a unifying of separate strands to create both a functional and beautiful whole.

That unifying of separate parts continues as we are told that the ten curtains were to be joined together in two main parts. Five curtains for one part, five for the other. From the following verses we will be made to understand that each curtain would be joined to its neighbor along the long sides. Thus the two composite pieces would become twenty-eight cubits by twenty, nearly a square. How the five curtains would be joined together is not clear. Perhaps they were stitched together, permanently bound together as one after first being formed as individuals. By whatever method, though, the ten had become two.

Note: It can be difficult to visualize some of the structures described in these verses.
