Genesis 25:29-32

29Once when Jacob was cooking some stew, Esau came in from the open country, famished.

30He said to Jacob, “Quick, let me have some of that red stew! I’m famished!” (That is why he was also called Edom. Edom means red. )

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

32“Look, I am about to die,” Esau said. “What good is the birthright to me?”
