Genesis 25:29-34

29Once, Jacob was preparing a meal when Esau, exhausted, came in from outdoors.

30So Esau said to Jacob, “Let me have the whole pot of red stuff to eat—that red stuff—I’m exhausted.” This is why he was called Edom.

31Jacob responded, “First, sell me your rights as firstborn.”

32“I’m about to die.” Esau said. “What good is my inheritance to me?”

33“First, swear an oath,” Jacob said. So Esau swore an oath to him and sold him his rights as firstborn.

34Then Jacob gave Esau a meal of bread and lentils. He ate and drank, and then he got up and left. This is how Esau showed his contempt for his rights as firstborn.
