Leviticus 27:8-10

21st Century King James Version

⁸ But if he be poorer than thy valuation, then he shall present himself before the priest and the priest shall value him; according to his ability who vowed shall the priest value him.

⁹ “‘And if it be a beast whereof men bring an offering unto the Lord, all that any man giveth of such unto the Lord shall be holy.

¹⁰ He shall not alter it nor change it, a good for a bad or a bad for a good; and if he shall at all change beast for beast, then it and the exchange thereof shall be holy.
