Genesis 25:30-32

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?”
