Exodus 26:7-9

American Standard Version

⁷ And thou shalt make curtains of goats’ hair for a tent over the tabernacle: eleven curtains shalt thou make them. ⁸ The length of each curtain shall be thirty cubits, and the breadth of each curtain four cubits: the eleven curtains shall have one measure. ⁹ And thou shalt couple five curtains by themselves, and six curtains by themselves, and shalt double over the sixth curtain in the forefront of the tent.
