'Walled' in the Bible

"'If a man sells a dwelling house in a walled city, then he may redeem it within a whole year after it has been sold. For a full year he shall have the right of redemption.

If it isn't redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him who bought it, throughout his generations. It shall not be released in the Jubilee.

He has walled up my way so that I can't pass, and has set darkness in my paths.

He has walled me about, that I can't go forth; he has made my chain heavy.

He has walled up my ways with cut stone; he has made my paths crooked.
