Bechorot 31a Cheapening that which is Sacred - הבכור והמעשר הנייתו לבעלים

From Matmonim: Daf Yomi by Rabbi David Lapin by R David Lapin.

Often we find that principles of spirituality and of economics overlap. That is an indication of their Truth.  The value of things is expressed not only by how we handle them but also  by the price we are willing to pay for them.
