Leviticus 25:29

²⁷then shall he calculate the years of his sale, and he shall give what is due to the man to whom he sold it, and he shall return to his possession.

²⁸But if his hand have not prospered sufficiently, so as that he should restore the money to him, then he that bought the possessions shall have them till the sixth year of the release; and it shall go out in the release, and the owner shall return to his possession.

— Leviticus 25:29 —

³⁰And if it be not ransomed until there be completed of its time a full year, the house which is in the walled city shall be surely confirmed to him that bought it, throughout his generations; and it shall not go out in the release.

³¹But the houses in the villages which have not a wall round about them, shall be reckoned as the fields of the country: they shall always be redeemable, and they shall go out in the release.
