Leviticus 27:12

And the priest shall value it, whether it be good or bad
Put a price upon it according to its worth, as it shall appear to him:

as thou valuest it, [who art] the priest, so shall it be;
that shall be the price at which it shall be sold, not to the owner or devoter of it, for he must give more, as appears from ( Leviticus 27:13 ) ; but, as Jarchi observes, to all other men who come to purchase it.
