Abraham's Descendants through Keturah
25 1 Abraham took another wife, and her name was Keturah. 2 She bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3 Jokshan became the father of Sheba, and Dedan. The sons of Dedan were Asshurim, Letushim, and Leummim. 4 The sons of Midian: Ephah, Epher, Hanoch, Abida, and Eldaah. All these were the children of Keturah. 5 Abraham gave all that he had to Isaac, 6 but to the sons of Abraham’s concubines, Abraham gave gifts. He sent them away from Isaac his son, while he yet lived, eastward, to the east country.
The Death and Burial of Abraham
7 These are the days of the years of Abraham’s life which he lived: one hundred seventy-five years. 8 Abraham gave up the spirit, and died in a good old age, an old man, and full of years, and was gathered to his people. 9 Isaac and Ishmael, his sons, buried him in the cave of Machpelah, in the field of Ephron, the son of Zohar the Hittite, which is before Mamre, 10 the field which Abraham purchased of the children of Heth. Abraham was buried there with Sarah, his wife.
11 It happened after the death of Abraham that God blessed Isaac, his son. Isaac lived by Beer Lahai Roi.
The Descendants of Ishmael
12 Now this is the history of the generations of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s handmaid, bore to Abraham. 13 These are the names of the sons of Ishmael, by their names, according to the order of their birth: the firstborn of Ishmael, Nebaioth, then Kedar, Adbeel, Mibsam, 14 Mishma, Dumah, Massa, 15 Hadad, Tema, Jetur, Naphish, and Kedemah. 16 These are the sons of Ishmael, and these are their names, by their villages, and by their encampments: twelve princes, according to their nations. 17 These are the years of the life of Ishmael: one hundred thirty-seven years. He gave up the spirit and died, and was gathered to his people. 18 They lived from Havilah to Shur that is before Egypt, as you go toward Assyria. He lived opposite all his relatives.
The Birth of Esau and Jacob
19 This is the history of the generations of Isaac, Abraham’s son. Abraham became the father of Isaac. 20 Isaac was forty years old when he took Rebekah, the daughter of Bethuel the Syrian of Paddan Aram, the sister of Laban the Syrian, to be his wife. 21 Isaac entreated Yahweh for his wife, because she was barren. Yahweh was entreated by him, and Rebekah his wife conceived. 22 The children struggled together within her. She said, “If it be so, why do I live?” She went to inquire of Yahweh. 23 Yahweh said to her,
“Two nations are in your womb.
Two peoples will be separated from your body.
The one people will be stronger than the other people.
The elder will serve the younger.” 24 When her days to be delivered were fulfilled, behold, there were twins in her womb. 25 The first came out red all over, like a hairy garment. They named him Esau. 26 After that, his brother came out, and his hand had hold on Esau’s heel. He was named Jacob. Isaac was sixty years old when she bore them.
Esau Sells His Birthright
29 Jacob boiled stew. Esau came in from the field, and he was famished. 30 Esau said to Jacob, “Please feed me with that same red stew, for I am famished.” Therefore his name was called Edom. 31 Jacob said, “First, sell me your birthright.” 32 Esau said, “Behold, I am about to die. What good is the birthright to me?” 33 Jacob said, “Swear to me first.”
He swore to him. He sold his birthright to Jacob. 34 Jacob gave Esau bread and stew of lentils. He ate and drank, rose up, and went his way. So Esau despised his birthright.
Isaac at Gerar
26 1 There was a famine in the land, besides the first famine that was in the days of Abraham. Isaac went to Abimelech king of the Philistines, to Gerar. 2 Yahweh appeared to him, and said, “Don’t go down into Egypt. Live in the land I will tell you about. 3 Sojourn in this land, and I will be with you, and will bless you. For to you, and to your seed, I will give all these lands, and I will establish the oath which I swore to Abraham your father. 4 I will multiply your seed as the stars of the sky, and will give to your seed all these lands. In your seed will all the nations of the earth be blessed, 5 because Abraham obeyed my voice, and kept my requirements, my commandments, my statutes, and my laws.”
6 Isaac lived in Gerar. 7 The men of the place asked him about his wife. He said, “She is my sister,” for he was afraid to say, “My wife,” lest, he thought, “the men of the place might kill me for Rebekah, because she is beautiful to look at.” 8 It happened, when he had been there a long time, that Abimelech king of the Philistines looked out at a window, and saw, and, behold, Isaac was caressing Rebekah, his wife. 9 Abimelech called Isaac, and said, “Behold, surely she is your wife. Why did you say, ‘She is my sister?’”
Isaac said to him, “Because I said, ‘Lest I die because of her.’” 10 Abimelech said, “What is this you have done to us? One of the people might easily have lain with your wife, and you would have brought guilt on us!” 11 Abimelech commanded all the people, saying, “He who touches this man or his wife will surely be put to death.”
12 Isaac sowed in that land, and reaped in the same year one hundred times what he planted. Yahweh blessed him. 13 The man grew great, and grew more and more until he became very great. 14 He had possessions of flocks, possessions of herds, and a great household. The Philistines envied him. 15 Now all the wells which his father’s servants had dug in the days of Abraham his father, the Philistines had stopped, and filled with earth. 16 Abimelech said to Isaac, “Go from us, for you are much mightier than we.” 17 Isaac departed from there, encamped in the valley of Gerar, and lived there. 18 Isaac dug again the wells of water, which they had dug in the days of Abraham his father. For the Philistines had stopped them after the death of Abraham. He called their names after the names by which his father had called them. 19 Isaac’s servants dug in the valley, and found there a well of springing water. 20 The herdsmen of Gerar argued with Isaac’s herdsmen, saying, “The water is ours.” He called the name of the well Esek, because they contended with him. 21 They dug another well, and they argued over that, also. He called its name Sitnah. 22 He left that place, and dug another well. They didn’t argue over that one. He called it Rehoboth. He said, “For now Yahweh has made room for us, and we will be fruitful in the land.” 23 He went up from there to Beersheba. 24 Yahweh appeared to him the same night, and said, “I am the God of Abraham your father. Don’t be afraid, for I am with you, and will bless you, and multiply your seed for my servant Abraham’s sake.” 25 He built an altar there, and called on the name of Yahweh, and pitched his tent there. There Isaac’s servants dug a well.
26 Then Abimelech went to him from Gerar, and Ahuzzath his friend, and Phicol the captain of his army. 27 Isaac said to them, “Why have you come to me, since you hate me, and have sent me away from you?” 28 They said, “We saw plainly that Yahweh was with you. We said, ‘Let there now be an oath between us, even between us and you, and let us make a covenant with you, 29 that you will do us no harm, as we have not touched you, and as we have done to you nothing but good, and have sent you away in peace.’ You are now the blessed of Yahweh.” 30 He made them a feast, and they ate and drank. 31 They rose up some time in the morning, and swore one to another. Isaac sent them away, and they departed from him in peace. 32 It happened the same day, that Isaac’s servants came, and told him concerning the well which they had dug, and said to him, “We have found water.” 33 He called it Shibah.  Therefore the name of the city is Beersheba  to this day.
26:33 Shibah means “oath” or “seven.”
26:33 Beersheba means “well of the oath” or “well of the seven”
