'Walled' in the Bible

‘Likewise, if a man sells a dwelling house in a walled city, then his redemption right remains valid until a full year from its sale; his right of redemption lasts a full year.

But if it is not bought back for him within the space of a full year, then the house that is in the walled city passes permanently to its purchaser throughout his generations; it does not revert in the jubilee.

Please, let us make a little walled upper chamber and let us set a bed for him there, and a table and a chair and a lampstand; and it shall be, when he comes to us, that he can turn in there.”

“He has walled up my way so that I cannot pass,And He has put darkness on my paths.

He has walled me in so that I cannot go out;He has made my chain heavy.
