Shemot 26:7-9

Orthodox Jewish Bible

⁷ And thou shalt make curtains of goat hair to be an Ohel over the Mishkan: eleven curtains shalt thou make.

⁸ The length of one curtain shall be thirty cubits, the width of one curtain four cubits: and the eleven curtains shall be all of the middah achat (same size).

⁹ And thou shalt join into one five curtains by themselves, and six curtains by themselves, and shalt fold the sixth curtain over the front of the Ohel.
