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.

Matthew Henry's Commentary on Leviticus 27:18

Commentary on Leviticus 27:14-25

(Read Leviticus 27:14-25)
