Genesis 25:27-30 New American Standard Bible (NASB)

27. When the boys grew up, Esau became a skillful hunter, a man of the field, but Jacob was a peaceful man, living in tents.

28. Now Isaac loved Esau, because he had a taste for game, but Rebekah loved Jacob.

29. When Jacob had cooked stew, Esau came in from the field and he was famished;

30. and Esau said to Jacob, "Please let me have a swallow of that red stuff there, for I am famished." Therefore his name was called Edom.
