1Now Abraham took another wife, whose name was Keturah. 2She bore to him Zimran and Jokshan and Medan and Midian and Ishbak and Shuah. 3Jokshan became the father of Sheba and Dedan. And the sons of Dedan were Asshurim and Letushim and Leummim. 4The sons of Midian were Ephah and Epher and Hanoch and Abida and Eldaah. All these were the sons of Keturah. 5Now Abraham gave all that he had to Isaac; 6but to the sons of his concubines, Abraham gave gifts while he was still living, and sent them away from his son Isaac eastward, to the land of the east.
7These are all the years of Abraham’s life that he lived, one hundred and seventy-five years.8Abraham breathed his last and died in a ripe old age, an old man and satisfied with life; and he was gathered to his people. 9Then his sons Isaac and Ishmael buried him in the cave of Machpelah, in the field of Ephron the son of Zohar the Hittite, facing Mamre, 10the field which Abraham purchased from the sons of Heth; there Abraham was buried with Sarah his wife. 11It came about after the death of Abraham, that God blessed his son Isaac; and Isaac lived by Beer-lahai-roi.
Genesis 25:1-11
27When the boys grew up, Esau became a skillful hunter, a man of the field, but Jacob was a peaceful man, living in tents. 28Now Isaac loved Esau, because he had a taste for game, but Rebekah loved Jacob. 29When Jacob had cooked stew, Esau came in from the field and he was famished; 30and 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. 31But Jacob said, “First sell me your birthright.”32Esau said, “Behold, I am about to die; so of what use then is the birthright to me?” 33And Jacob said, “First swear to me”; so he swore to him, and sold his birthright to Jacob. 34Then Jacob gave Esau bread and lentil stew; and he ate and drank, and rose and went on his way. Thus Esau despised his birthright.
