Leviticus 27:9-11

New King James Version

⁹ ‘If it is an animal that men may bring as an offering to the Lord, all that anyone gives to the Lord shall be holy. ¹⁰ He shall not substitute it or exchange it, good for bad or bad for good; and if he at all exchanges animal for animal, then both it and the one exchanged for it shall be ^(A)holy. ¹¹ If it is an unclean animal which they do not offer as a sacrifice to the Lord, then he shall present the animal before the priest;
