Leviticus 27:18-20 Darby Translation (DARBY)
18 but if he hallow his field after the jubilee, then the priest shall reckon unto him the money according to the years that remain, until the year of the jubilee; and there shall be a reduction from thy valuation.
19 And if he that hallowed the field will in any wise redeem it, he shall add the fifth of the money of thy valuation unto it, and it shall be assured to him;
20 but if he do not redeem the field, or if he sell the field to another man, it cannot be redeemed any more;
Leviticus 27:18-20 New International Version (NIV)
18 But if they dedicate a field after the Jubilee, the priest will determine the value according to the number of years that remain until the next Year of Jubilee, and its set value will be reduced. 19 If the one who dedicates the field wishes to redeem it, they must add a fifth to its value, and the field will again become theirs. 20 If, however, they do not redeem the field, or if they have sold it to someone else, it can never be redeemed.
