Lev 27:16-25

16If a person consecrates to the Lord any inherited landholding, its assessment shall be in accordance with its seed requirements: fifty shekels of silver to a homer of barley seed.17If the person consecrates the field as of the year of jubilee, that assessment shall stand;18but if the field is consecrated after the jubilee, the priest shall compute the price for it according to the years that remain until the year of jubilee, and the assessment shall be reduced.19And if the one who consecrates the field wishes to redeem it, then one-fifth shall be added to its assessed value, and it shall revert to the original owner;20but if the field is not redeemed, or if it has been sold to someone else, it shall no longer be redeemable.21But when the field is released in the jubilee, it shall be holy to the Lord as a devoted field; it becomes the priest's holding.22If someone consecrates to the Lord a field that has been purchased, which is not a part of the inherited landholding,23the priest shall compute for it the proportionate assessment up to the year of jubilee, and the assessment shall be paid as of that day, a sacred donation to the Lord.24In the year of jubilee the field shall return to the one from whom it was bought, whose holding the land is.25All assessments shall be by the sanctuary shekel: twenty gerahs shall make a shekel.
