Genesis 25:33-34

New International Reader's Version

³³ But Jacob said, “First promise to sell me your rights.” So Esau promised to do it. He sold Jacob all the rights that belonged to him as the oldest son.

³⁴ Then Jacob gave Esau some bread and some lentil stew. Esau ate and drank. Then he got up and left.

So Esau didn’t value the rights that belonged to him as the oldest son.
