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 a man dedicates to God part of his family land, its value is to be set according to the amount of seed that is needed for it at the rate of fifty shekels of silver to six bushels of barley seed.

17 If he dedicates his field during the year of Jubilee, the set value stays.

18 But if he dedicates it after the Jubilee, the priest will compute the value according to the years left until the next Jubilee, reducing the value proportionately.

19 If the one dedicating it wants to buy it back, he must add twenty percent to its valuation, and then it's his again.

20 But if he doesn't redeem it or sells the field to someone else, it can never be bought back.
