Genesis 25:29

27The boys grew. Esau was a skillful hunter, a man of the field. Jacob was a quiet man, living in tents.

28Now Isaac loved Esau, because he ate his venison. Rebekah loved Jacob.

29Jacob boiled stew. Esau came in from the field, and he was famished.

30Esau said to Jacob, “Please feed me with some of that red stew, for I am famished.” Therefore his name was called Edom.

31Jacob said, “First, sell me your birthright.”
