Exodus 38:13-17

And for the east side eastward fifty cubits.

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.

All the hangings of the court round about were of fine twined linen.

And the sockets for the pillars were of brass; the hooks of the pillars and their fillets of silver; and the overlaying of their chapiters of silver; and all the pillars of the court were filleted with silver.
