Leviticus 27:16

Possession, or inheritance. If he had only purchased the field, he could not, by his vow, transfer the property of it to the priests beyond the year of jubilee, ver. 22. --- Seed, not of the produce, which is uncertain. The goodness of the soil must also be considered. --- Silver: which rent must be paid every year, except on those of rest, when the earth was not cultivated. (Calmet)
