"Anyone who sells a house in a walled city retains the right of redemption a full year after its sale. During that time the seller may redeem it." (NIV)
If a man sells a dwelling house in a fortified city, he may redeem it within a whole year after it is sold; for a full year he may have the right of redemption. (AMP)
And if a man sell a dwelling house in a walled city, then he may redeem it within a whole year after it is sold; within a full year may he redeem it. (KJV)
