Genesis 25:29-34

One day Jacob was cooking a stew. Esau came in from the field, starved. Esau said to Jacob, “Give me some of that red stew—I’m starved!” That’s how he came to be called Edom (Red). Jacob said, “Make me a trade: my stew for your rights as the firstborn.” Esau said, “I’m starving! What good is a birthright if I’m dead?” Jacob said, “First, swear to me.” And he did it. On oath Esau traded away his rights as the firstborn. Jacob gave him bread and the stew of lentils. He ate and drank, got up and left. That’s how Esau shrugged off his rights as the firstborn. * * *
