Leviticus 27:19-27

19If he who dedicated the field would ever redeem it, then he is to add a fifth of the money of your valuation to it, and it will remain his.

20But if he will not redeem the field, or if he has sold the field to someone else, it may not be redeemed anymore.

21But the field, when it is released in the Jubilee, will be holy to Adonai as a consecrated field. It will be owned by the kohanim.

22“Now if one consecrates to Adonai a field that he has bought, which is not from the fields of his possession,

23then the kohen is to calculate for him the worth of your valuation up to the Year of Jubilee, and give your valuation on that day as a holy thing to Adonai.

24In the Year of Jubilee the field is to return to the one from whom it was bought, to the one to whom the possession of the land belongs.

25All your valuations shall be according to the shekel of the Sanctuary, 20 gerahs to the shekel.

26“But the firstborn among animals, which is made a firstborn to Adonai, may not be dedicated by anyone. Whether an ox or sheep, it belongs to Adonai.

27If it is an unclean animal, then he is to buy it back according to your valuation, and add a fifth of the value to it. But if it is not redeemed, then it is to be sold according to your valuation.
