Esau sells his birthright
Genesis 25:27–34; Hebrews 12:16–17
Coming in famished from the field, Esau traded his rights as firstborn to Jacob for a bowl of lentil stew.
Jacob gave Esau bread and lentil stew. He ate and drank, rose up, and went his way. So Esau despised his birthright.
Genesis 25:34 (World English Bible)
The birthright meant leadership of the family and a double share of the inheritance, and in this family it carried God's covenant promise. Esau treated it as worth less than one meal. Hebrews holds him up as a warning against trading lasting things for momentary appetites.
Dating notes
Scripture gives no year, only that the boys had grown up. Ussher doesn't date it. The date shown follows a Jewish tradition (Talmud, Bava Batra 16b) that Jacob cooked the lentils as mourning food on the day Abraham died; treat it as an estimate.
