Genesis 25:29-31 Darby Translation (DARBY)
29 And Jacob had cooked a dish; and Esau came from the field, and he was faint.
30 And Esau said to Jacob, Feed me, I pray thee, with the red—the red thing there, for I am faint. Therefore was his name called Edom.
31 And Jacob said, Sell me now thy birthright.
