Exodus 27:9, 12, 14-15

And thou shalt make the court of the tabernacle: for the south side southward there shall be hangings for the court of fine twined linen of an hundred cubits long for one side

And for the breadth of the court on the west side shall be hangings of fifty cubits: their pillars ten, and their sockets ten.

The hangings of one side of the gate shall be fifteen cubits: their pillars three, and their sockets three. And on the other side shall be hangings fifteen cubits: their pillars three, and their sockets three.
