Exodus 26:1-3

“Moreover, you shall make the tabernacle with ten curtains of fine twined linen and blue and purple and scarlet yarns; you shall make them with cherubim skillfully worked into them. The length of each curtain shall be twenty-eight cubits, and the breadth of each curtain four cubits; all the curtains shall be the same size. Five curtains shall be coupled to one another, and the other five curtains shall be coupled to one another.
