Genesis 25:32-34Christian Standard Bible (CSB)
32 “Look,” said Esau, “I’m about to die, so what good is a birthright to me?”
33 Jacob said, “Swear to me first.” So he swore to Jacob and sold his birthright to him. 34 Then Jacob gave bread and lentil stew to Esau; he ate, drank, got up, and went away. So Esau despised his birthright.
