This is not a quiz type question but it is a question on Tanach.
Esav sold the bechorah to Yaakov. My question is how Yaakov able to accept this? There is a concept of not bieng allowed to sell something for more than 1/6 of its market value. So how could Yaakov accept it for more than Esav would be allowed to sell it, wouldnt he be allowing Esav to commit an aveirah? The bchorah was worth way more than a bowl of lint soup.
