Leviticus 27:18-28

¹⁸But if he sets apart his field after the year of Jubilee, then the priest must calculate the value of the field by the number of years that remain until the next year of Jubilee, and the valuation of it must be reduced.

¹⁹If the man who set apart the field wishes to redeem it, then he must add a fifth to the valuation, and it will belong to him.

²⁰If he does not redeem the field, or if he has sold the field to another man, it cannot be redeemed any more.

²¹Instead, the field, when it is released in the year of Jubilee, will be a holy gift to Yahweh, like the field that has been completely given to Yahweh. It will belong to the priest.

²²If a man sets apart a field that he has bought, but that field is not part of his family's land,

²³then the priest will figure the valuation of it up to the year of Jubilee, and the man must pay its value on that day as a holy gift to Yahweh.

²⁴In the year of Jubilee, the field will return to the man from whom it was bought, to the land's owner.

²⁵All the valuations must be set by the weight of the sanctuary shekel. Twenty gerahs must be the equivalent of one shekel.

²⁶No one may set apart the firstborn among animals, since the firstborn already belongs to Yahweh; whether ox or sheep, it is Yahweh's.

²⁷If it is an unclean animal, then the owner may buy it back at the valuation of it, and a fifth must be added to that value. If the animal is not redeemed, then it is to be sold at the set value.

²⁸But nothing that a man devotes to Yahweh, from all that he has, whether human or animal, or his family land, may be sold or redeemed. Everything that is devoted is very holy to Yahweh.
