Leviticus 27:18

18 If you dedicate it any time later, the priest shall estimate the cash value according to the number of years left until the next Year of Restoration, and set a reduced price.

Leviticus 27:18 Meaning and Commentary

Leviticus 27:18

But if he sanctify his field after the jubilee
Some years after it, more or fewer, or it may be, when half way towards another jubilee, or nearer:

then the priest shall reckon unto him the money according to the years
that remain, even unto the year of the jubilee;
thus, for instance, if it only required an homer of barley to sow it, and the whole value of it from jubilee to jubilee was but fifty shekels of silver; then supposing it to be sanctified in the middle of the fifty years, or at twenty five years' end, it was to be reckoned at twenty five shekels, and sold for that money, and so in proportion, reckoning a shekel for a year:

and it shall be abated from thy estimation;
not the year of jubilee, but a shekel for every year was to be deducted from the original value of fifty shekels, according to the number of years that had passed or were to come.

Leviticus 27:18 In-Context

16 If any of you dedicate part of your land to the Lord, the price shall be set according to the amount of seed it takes to sow it, at the rate of ten pieces of silver per bushel of barley.
17 If you dedicate the land immediately after a Year of Restoration, the full price applies.
18 If you dedicate it any time later, the priest shall estimate the cash value according to the number of years left until the next Year of Restoration, and set a reduced price.
19 If you wish to buy your field back, you must pay the price plus an additional 20 percent.
20 If you sell the field to someone else without first buying it back from the Lord, you lose the right to buy it back.
