Leviticus 27:25

21 When the field is released in the Jubilee, it will become holy, like a field devoted to the LORD; it becomes the property of the priests.

22 Now if a man consecrates to the LORD a field he has purchased, which is not a part of his own property,

23 then the priest shall calculate for him the value up to the Year of Jubilee, and the man shall pay the assessed value on that day as a sacred offering to the LORD.

24 In the Year of Jubilee the field shall return to the one from whom it was bought—the original owner of the land.

25 Every valuation will be according to the sanctuary shekel, twenty gerahs to the shekel.

26 But no one may consecrate a firstborn of the livestock, because a firstborn belongs to the LORD. Whether it is an ox or a sheep, it is the LORD’s.

27 But if it is among the unclean animals, then he may redeem it according to your valuation and add a fifth of its value. If it is not redeemed, then it shall be sold according to your valuation.

28 Nothing that a man sets apart to the LORD from all he owns—whether a man, an animal, or his inherited land—can be sold or redeemed; everything so devoted is most holy to the LORD.

29 No person set apart for destruction may be ransomed; he must surely be put to death.
