Exodus 27:10-12

They will be held up by twenty posts set securely in twenty bronze bases. Hang the curtains with silver hooks and rings. Make the curtains the same on the north side—150 feet of curtains held up by twenty posts set securely in bronze bases. Hang the curtains with silver hooks and rings. The curtains on the west end of the courtyard will be 75 feet long, supported by ten posts set into ten bases.
