Exodus 38:13

For the north side one hundred cubits, their pillars twenty, and their sockets twenty, of brass; the hooks of the pillars, and their fillets, of silver.

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 for the one side were fifteen cubits; their pillars three, and their sockets three;

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