25 All prices shall be set according to the official standard.
26 The first-born of an animal already belongs to the Lord, so no one may dedicate it to him as a freewill offering. A calf, a lamb, or a kid belongs to the Lord,
27 but the first-born of an unclean animal may be bought back at the standard price plus an additional 20 percent. If it is not bought back, it may be sold to someone else at the standard price.
28 None of you may sell or buy back what you have unconditionally dedicated to the Lord, whether it is a human being, an animal, or land. It belongs permanently to the Lord.
29 Not even human beings who have been unconditionally dedicated may be bought back; they must be put to death.
30 One tenth of all the produce of the land, whether grain or fruit, belongs to the Lord.
31 If you wish to buy any of it back, you must pay the standard price plus an additional 20 percent.
