In the year of the jubile the field shall return unto him of whom it was bought, even to him to whom the possession of the land did belong.
Leviticus 27:20
and if he do not redeem the field, or if he hath sold the field to another man, it is not redeemed any more;
Leviticus 25:28
'And if his hand hath not found sufficiency to give back to him, then hath his sold thing been in the hand of him who buyeth it till the year of jubilee; and it hath gone out in the jubilee, and he hath returned to his possession.
