Genesis 25:27-34 New American Standard Bible (NASB)
27 When the boys grew up, Esau became a skillful hunter, a man of the field, but Jacob was a [a]peaceful man, [b]living in tents. 28 Now Isaac loved Esau, because [c]he had a taste for game, but Rebekah loved Jacob. 29 When Jacob had cooked stew, Esau came in from the field and he was [d]famished; 30 and Esau said to Jacob, “Please let me have a swallow of [e]that red stuff there, for I am [f]famished.” Therefore his name was called [g]Edom. 31 But Jacob said, “[h]First sell me your birthright.” 32 Esau said, “Behold, I am about to die; so of what use then is the birthright to me?” 33 And Jacob said, “[i]First swear to me”; so he swore to him, and sold his birthright to Jacob. 34 Then Jacob gave Esau bread and lentil stew; and he ate and drank, and rose and went on his way. Thus Esau despised his birthright.
