Leviticus 27:27-29

Evangelical Heritage Version

²⁷ But if it is one of the unclean livestock, he may buy it back at its set value plus one-fifth. If it is not redeemed, it may be sold at its set value.

²⁸ However, if anyone devotes anything that belongs to him to the Lord unconditionally, whether it is a human being or livestock or any part of his landholding, it may not be sold and may not be redeemed. Everything devoted unconditionally is most holy to the Lord.

²⁹ Any person who has been devoted to destruction may not be ransomed. He must certainly be put to death.
