'Walled' in the Bible

" 'And if a man sells {a residential house in a walled city}, then it shall be his redemption until completing {a year after his selling}; its redemption {shall last} {a year}.

But if it is not redeemed {before a full year has passed}, then the house that [is] {in the walled city} shall belong to the buyer in perpetuity throughout his generations; it shall not go out [of the buyer's hand] in the Jubilee.

He has walled up my way so that I cannot pass; and he has set darkness upon my paths.
