Exodus 26:1-3

“Moreover, you shall make the tabernacle with ten curtains of fine twisted linen and violet, purple, and scarlet material; you shall make them with cherubim, the work of a skilled embroiderer.

The length of each curtain shall be twenty-eight cubits, and the width of each curtain four cubits; all the curtains shall have the same measurements.

Five curtains shall be joined to one another, and the other five curtains shall be joined to one another.
