Genesis 25:29-34

29Now Jacob cooked some stew, and when Esau came in from the open fields, he was famished.

30So 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.)

31But Jacob replied, “First sell me your birthright.”

32“Look,” said Esau, “I’m about to die! What use is the birthright to me?”

33But Jacob said, “Swear an oath to me now.” So Esau swore an oath to him and sold his birthright to Jacob.

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