Genesis 25:24-26, 33-34

When her time to give birth came, sure enough, there were twins in her womb. The first came out reddish, as if snugly wrapped in a hairy blanket; they named him Esau (Hairy). His brother followed, his fist clutched tight to Esau’s heel; they named him Jacob (Heel). Isaac was sixty years old when they were born.

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. * * *
