Exodus 27:9-12

9You are also to make a courtyard for the tabernacle. On the south side of the courtyard make curtains of finely spun linen, a hundred cubits long1 on one side, 10with twenty posts and twenty bronze bases, and silver hooks and bands on the posts.

11Likewise there are to be curtains on the north side, a hundred cubits long, with twenty posts and twenty bronze bases, and with silver hooks and bands on the posts. 12The curtains on the west side of the courtyard shall be fifty cubits wide,2 with ten posts and ten bases.
