'Arched' in the Bible

That you made for yourself an arched room in every open place.

For you have made your arched room at the top of every street, and your high place in every open place; though you were not like a loose woman in getting together your payment.

I will give you into their hands, and your arched room will be overturned and your high places broken down; they will take your clothing off you and take away your fair jewels: and when they have done, you will be uncovered and shamed.
