Exodus 38:17-20

The sockets for the pillars were bronze, the hooks of the pillars and their bands were silver, and the overlay of their capitals was silver; and all the pillars of the court had bands of silver. The screen for the gate of the court was woven of blue, purple, and scarlet thread, and of fine woven linen. The length was twenty cubits, and the height along its width was five cubits, corresponding to the hangings of the court. And there were four pillars with their four sockets of bronze; their hooks were silver, and the overlay of their capitals and their bands was silver. All the pegs of the tabernacle, and of the court all around, were bronze.
