Leviticus 27:10-12

English Standard Version

^10 (A)He shall not exchange it or make a substitute for it, good for bad, or bad for good; and if he does in fact substitute one animal for another, then both it and the substitute shall be holy. ¹¹ And if it is any unclean animal that may not be offered as an offering to the Lord, then he shall stand the animal before the priest, ¹² and the priest shall value it as either good or bad; as the priest values it, so it shall be.
