Exodus 38:19 (KJV)

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.

And the hanging for the gate of the court was needlework, of blue, and purple, and scarlet, and fine twined linen: and twenty cubits was the length, and the height in the breadth was five cubits, answerable to the hangings of the court.

And their pillars were four, and their sockets of brass four; their hooks of silver, and the overlaying of their chapiters and their fillets of silver.

And all the pins of the tabernacle, and of the court round about, were of brass.

This is the sum of the tabernacle, even of the tabernacle of testimony, as it was counted, according to the commandment of Moses, for the service of the Levites, by the hand of Ithamar, son to Aaron the priest.
