Leviticus 27:14,15

The case of houses16 25. The case of lands

The vow, as regards its duration, is thus limited to a maximum of 50 years, being determined by the distance of the year of Jubile. When that year arrives, the field shall return to the owner, to be disposed of as he pleases. But even in the meantime, on payment of a defined sum of redemption-money, the field shall remain in the enjoyment of the owner, and the estimate for the purpose shall be at the rate of fifty shekels of silver for the amount of land (about 3 8/4 acres, according to Kennedy, ad loc.) which would yield one homer (about eleven bushels) of barley, with an abatement in proportion to the number of years to run before the next Jubile. In order to obtain the enjoyment of the field, however, the owner must pay a further sum amounting to one-fifth of the redemption-money. In case the owner do not desire to redeem, or have alienated the land by selling it to another, the law of Jubile is not to operate; the land shall become the possession of the priest. In the case of a man's vowing land which is his by purchase and not by inheritance, that purchase shall not hold good beyond the Jubile, the purchaser redeeming it in the meantime by a payment calculated on the same principle as above.
