Genesis 25:27-30

27When the boys grew up, Esau was an able and skilled hunter, a man of the outdoors, but Jacob was a quiet and peaceful man, living in tents.

28Now Isaac loved [and favored] Esau, because he enjoyed eating his game, but Rebekah loved [and favored] Jacob.

29Jacob had cooked [reddish-brown lentil] stew [one day], when Esau came from the field and was famished;

30and Esau said to Jacob, “Please, let me have a quick swallow of that red stuff there, because I am exhausted and famished.” For that reason Esau was [also] called Edom (Red).
