Leviticus 27:12 in the King James Version
And the priest shall value it, whether it be good or bad: as thou valuest it, who art the priest, so shall it be.
Context
11 If it is any unclean animal, of which they do not offer as an offering to the LORD, then he shall set the animal before the priest;
12 and the priest shall evaluate it, whether it is good or bad. As the priest evaluates it, so it shall be.
13 But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.
