Leviticus 27:20-25

²⁰But if he will not redeem the field, or if he have sold the field to another man, it shall not be redeemed any more:

²¹But the field, when it would have gone out at the Jubilee, shall be consecrated before the Lord as a field devoted (hekel cherema); the possession of it shall be to the priest.

²²And if a man will consecrate before the Lord a field which he hath bought, and which is not of the fields of his inheritance,

²³then the priest shall reckon the sum (receipt) of its value until the year of Jubilee, and he shall give the price of it in that day, a holy thing before the Lord.

²⁴In the year of Jubilee the field shall return unto him who sold it, to whom the possession of the land had belonged.

²⁵And every valuation shall be in the shekel of the sanctuary, twenty maheen before the Lord.
