The east end of the courtyard, the front, will also be 75 feet long. The courtyard entrance will be on the east end, flanked by two curtains. The curtain on the right side will be 22-1/2 feet long, supported by three posts set into three bases. The curtain on the left side will also be 22-1/2 feet long, supported by three posts set into three bases. “For the entrance to the courtyard, make a curtain that is 30 feet long. Make it from finely woven linen, and decorate it with beautiful embroidery in blue, purple, and scarlet thread. Support it with four posts, each securely set in its own base.
