Leviticus 27:10-12

Darby Translation

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

¹¹ And if it be any unclean beast, of which they do not bring an offering unto Jehovah, then he shall present the beast before the priest;

¹² and the priest shall value it, [judging] between good and bad: according to the valuation of the priest, so shall it be.
