Leviticus 25:27 (KJV)

If thy brother be waxen poor, and hath sold away some of his possession, and if any of his kin come to redeem it, then shall he redeem that which his brother sold.

And if the man have none to redeem it, and himself be able to redeem it;

Then let him count the years of the sale thereof, and restore the overplus unto the man to whom he sold it; that he may return unto his possession.

But if he be not able to restore it to him, then that which is sold shall remain in the hand of him that hath bought it until the year of jubile: and in the jubile it shall go out, and he shall return unto his possession.

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.
