Leviticus 27:18

18 and if after the jubilee he sanctify his field, then hath the priest reckoned to him the money according to the years which are left, unto the year of the jubilee, and it hath been abated from thy valuation.

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 `And if of the field of his possession a man sanctify to Jehovah, then hath thy valuation been according to its seed; a homer of barley-seed at fifty shekels of silver;
17 if from the year of the jubilee he sanctify his field, according to thy valuation it standeth;
18 and if after the jubilee he sanctify his field, then hath the priest reckoned to him the money according to the years which are left, unto the year of the jubilee, and it hath been abated from thy valuation.
19 `And if he really redeem the field -- he who is sanctifying it -- then he hath added a fifth of the money of thy valuation to it, and it hath been established to him;
20 and if he do not redeem the field, or if he hath sold the field to another man, it is not redeemed any more;
