Genesis 25:28-34

25:28 Isaac loved Esau because he had a taste for fresh game, but Rebekah loved Jacob.

25:29 Now Jacob cooked some stew, and when Esau came in from the open fields, he was famished. 25:30 So Esau said to Jacob, “Feed me some of the red stuff – yes, this red stuff – because I’m starving!” (That is why he was also called Edom.)

25:31 But Jacob replied, “First sell me your birthright.” 25:32 “Look,” said Esau, “I’m about to die! What use is the birthright to me?” 25:33 But Jacob said, “Swear an oath to me now.” So Esau swore an oath to him and sold his birthright to Jacob.

25:34 Then Jacob gave Esau some bread and lentil stew; Esau ate and drank, then got up and went out. So Esau despised his birthright.
