Leviticus 27:21-24

but the field, when it goeth out in the jubile, shall be holy unto the LORD, as a field devoted; the possession thereof shall be the priest's. And if he sanctify unto the LORD a field which he hath bought, which is not of the field of his possession; then the priest shall reckon unto him the worth of thy estimation unto the year of jubile: and he shall give thine estimation in that day, as a holy thing unto the LORD. In the year of jubile the field shall return unto him of whom it was bought, even to him to whom the possession of the land belongeth.
