Exodus 27:11

So for the north side there shall be hangings a hundred cubits long with their twenty pillars; and the twenty bases of them shall be of brass, and the links and the fillets of these pillars and their bases shall be overlaid with silver.

Thus shall there be to the side toward the north curtains of a hundred cubits in length; and their pillars twenty, and their sockets twenty of brass, and the rings and the clasps of the pillars, and their sockets overlaid with silver.
