Exodus 27:12

10 with twenty posts and twenty bronze bases, and silver hooks and bands on the posts.

11 Likewise 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.

The curtains on the west side of the courtyard shall be fifty cubits wide, with ten posts and ten bases.

13 The east side of the courtyard, toward the sunrise, is to be fifty cubits wide.

14 Make the curtains on one side fifteen cubits long, with three posts and three bases,

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
