Exodus 38:13

And for the north side the hangings were an hundred cubits, their pillars were twenty, and their sockets of brass twenty; the hooks of the pillars and their fillets of silver.

And for the west side were hangings of fifty cubits, their pillars ten, and their sockets ten; the hooks of the pillars and their fillets of silver.

The hangings of the one side of the gate were fifteen cubits; their pillars three, and their sockets three.

And for the other side of the court gate, on this hand and that hand, were hangings of fifteen cubits; their pillars three, and their sockets three.
