Leviticus 27:20-25

²⁰but if he will not again-buy it, but it is sold to any other man, he that avowed it shall never be able to again-buy it;

²¹for when the day of jubilee cometh, that field shall be hallowed to the Lord, and the possession hallowed pertaineth to the right of priests.

²²If the field is bought, and is not of the possession of greater men, that is, of ancestors, and it is hallowed to the Lord,

²³the priest shall determine the price by the number of years till to the jubilee, and he that avowed the field shall give the price thereof to the Lord;

²⁴forsooth in the jubilee it shall turn again to the former lord that sold it, and he shall have it into the heritage of his possession.

²⁵All the appraising, or value, shall be weighed by the shekel of the saintuary; a shekel hath twenty half-pence.
