Genesis 25:27-31 New American Bible, Revised Edition (NABRE)

27. When the boys grew up, Esau became a skillful hunter, a man of the open country; whereas Jacob was a simple man, who stayed among the tents.

28. Isaac preferred Esau, because he was fond of game; but Rebekah preferred Jacob.

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

30. He said to Jacob, “Let me gulp down some of that red stuff; I am famished.” That is why he was called Edom.

31. But Jacob replied, “First sell me your right as firstborn.”
