Exodus 38:17-20

And the bases for the pillars were of bronze, but the hooks of the pillars and their fillets were of silver. The overlaying of their capitals was also of silver, and all the pillars of the court were filleted with silver. And the screen for the gate of the court was embroidered with needlework in blue and purple and scarlet yarns and fine twined linen. It was twenty cubits long and five cubits high in its breadth, corresponding to the hangings of the court. And their pillars were four in number. Their four bases were of bronze, their hooks of silver, and the overlaying of their capitals and their fillets of silver. And all the pegs for the tabernacle and for the court all around were of bronze.
