Leviticus 27:9-13

9“If ⌞the vow⌟ is to give the kind of animal that people offer to the Lord, it will be considered holy.

10Don’t exchange or substitute animals, a good one for a bad one or a bad one for a good one. If you do exchange one animal for another, then both animals will be holy.

11If it is an unclean animal that cannot be brought to the Lord as an offering, bring it in front of the priest.

12The priest will determine what its value is. The value will be whatever the priest decides.

13If you want to buy it back, you must pay its full value plus one-fifth more.
