Exodus 26:1-3

“Moreover you shall make the tabernacle with ten curtains of fine woven linen and blue, purple, and scarlet thread; with artistic designs of cherubim you shall weave them. The length of each curtain shall be twenty-eight cubits, and the width of each curtain four cubits. And every one of the curtains shall have the same measurements. Five curtains shall be coupled to one another, and the other five curtains shall be coupled to one another.
