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 person consecrates to the Lord any inherited landholding, its assessment shall be in accordance with its seed requirements: fifty shekels of silver to a homer of barley seed.
17 If the person consecrates the field as of the year of jubilee, that assessment shall stand;
18 but if the field is consecrated after the jubilee, the priest shall compute the price for it according to the years that remain until the year of jubilee, and the assessment shall be reduced.
19 And if the one who consecrates the field wishes to redeem it, then one-fifth shall be added to its assessed value, and it shall revert to the original owner;
20 but if the field is not redeemed, or if it has been sold to someone else, it shall no longer be redeemable.
