Exodus 26:1-3

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

2The 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.

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