1Abraham took another wife, and her name was Keturah. 2She bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3Jokshan became the father of Sheba, and Dedan. The sons of Dedan were Asshurim, Letushim, and Leummim. 4The sons of Midian were Ephah, Epher, Hanoch, Abida, and Eldaah. All these were the children of Keturah. 5Abraham gave all that he had to Isaac, 6but Abraham gave gifts to the sons of Abraham’s concubines. While he still lived, he sent them away from Isaac his son, eastward, to the east country. 7These are the days of the years of Abraham’s life which he lived: one hundred seventy-five years. 8Abraham gave up his spirit, and died at a good old age, an old man, and full of years, and was gathered to his people. 9Isaac and Ishmael, his sons, buried him in the cave of Machpelah, in the field of Ephron, the son of Zohar the Hittite, which is near Mamre, 10the field which Abraham purchased from the children of Heth. Abraham was buried there with Sarah, his wife. 11After the death of Abraham, God blessed Isaac, his son. Isaac lived by Beer Lahai Roi.
12Now this is the history of the generations of Ishmael, Abraham’s son, whom Hagar the Egyptian, Sarah’s servant, bore to Abraham. 13These 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, 14Mishma, Dumah, Massa, 15Hadad, Tema, Jetur, Naphish, and Kedemah. 16These are the sons of Ishmael, and these are their names, by their villages, and by their encampments: twelve princes, according to their nations. 17These are the years of the life of Ishmael: one hundred thirty-seven years. He gave up his spirit and died, and was gathered to his people. 18They lived from Havilah to Shur that is before Egypt, as you go toward Assyria. He lived opposite all his relatives.
19This is the history of the generations of Isaac, Abraham’s son. Abraham became the father of Isaac. 20Isaac 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. 21Isaac entreated Yahweh for his wife, because she was barren. Yahweh was entreated by him, and Rebekah his wife conceived. 22The children struggled together within her. She said, “If it is like this, why do I live?” She went to inquire of Yahweh. 23Yahweh 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.”
24When her days to be delivered were fulfilled, behold, there were twins in her womb. 25The first came out red all over, like a hairy garment. They named him Esau. 26After 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.
27The boys grew. Esau was a skillful hunter, a man of the field. Jacob was a quiet man, living in tents. 28Now Isaac loved Esau, because he ate his venison. Rebekah loved Jacob. 29Jacob boiled stew. Esau came in from the field, and he was famished. 30Esau said to Jacob, “Please feed me with some of that red stew, for I am famished.” Therefore his name was called Edom.
31Jacob said, “First, sell me your birthright.”
32Esau said, “Behold, I am about to die. What good is the birthright to me?”
33Jacob said, “Swear to me first.”
He swore to him. He sold his birthright to Jacob. 34Jacob gave Esau bread and lentil stew. He ate and drank, rose up, and went his way. So Esau despised his birthright.
We first encounter Abraham (father of many nations) as Abram (great father) in Genesis 11:26-31). He was the son of Terah, brother of Nahor and Haran, and uncle of Lot. Abram's brother Haran died while Abram was still in Ur of the Chaldees (Gen 11:28), where also he married Sarai, his half-sister. We discover toward the end of Genesis 11 that his father Terah left Ur, and went to the land of Canaan, via a city named Harana, where Terah died.
The story of Abraham becomes important in chapter 12, in which we are introduced to important biblical characters, locations, and events that set the stage for the remainder of the Bible. Yahweh came to Abram was commanded him to go to a land that He would show him. In this passage, Yahweh sets forth and unilateral and unconditional covenant, in which He promised to make from him a great nation, make his name great, and through him bless all of the families of the earth.[1]
"Abraham (Abram) was first of the patriarchs, father of Isaac and Ishmael, grandfather of Jacob and the traditional ancestor of the Jewish people. Abraham (originally Abram, which means "exalted father") came from Ur in Mesopotamia. His father, Terah, took him (with his wife, Sarah, and his nephew, Lot) to Haran. God called Abraham to leave this new home and to find another home elsewhere in Canaan. After a brief stay in Egypt, Abraham settled near Hebron where he became involved in a local political quarrel when Lot was taken prisoner by an alliance of four eastern chieftains. Abraham launched a successful attack against this confederacy and on his victorious return encountered the mysterious Melchizedek, king of Salem, to whom he gave a tenth of all the spoil he had taken in the battle.
For many years of their marriage, he and Sarah were childless, but God assured Abraham that he would eventually become the father of a great nation. Sarah disbelieved and persuaded Abraham to beget a child by her maid, Hagar, who bore him his first son, Ishmael. When Abraham was ninety-nine years old, God appeared to him, and instituted with him a covenant of circumcision, giving him the new name of Abraham (meaning "father of a multitude") and told him that a son, to be named Isaac was shortly to be born to Sarah. When the boy was in his childhood, God ordered Abraham to take him up to a mountain in the land of Moriah and offer him up as a sacrificial victim. Abraham prepared to do so, but was prevented at the last moment from carrying out the sacrifice, and told that he would be blessed for his faithfulness in being ready to offer up his son.
When Sarah died Abraham bought the plot of ground (the field of Ephron in Machpelah) that became the burial place for many generations of his descendants. He subsequently made arrangements for the marriage of Isaac, and took another wife, Keturah, who bore him Zimran, Medan, Midian, Ishbak and Shuah. At the age of one hundred and seventy five, Abraham died and was buried in Machpelah.
The principal narrative of the part of Genesis dealing with Abraham's history is interrupted in various places by other stories involving the patriarch. These include the parallel stories of his sojourns in Egypt and in Gerar. On both occasions Abraham lied about his relations with Sarah, jeopardising the fulfilment of God's promise (as both Pharaoh and Abimelech intended to take Sarah for themselves), while protecting himself. Both times God intervened to save him from the consequences of his deception. In another story we read of Abraham's intercession on behalf of the cities of Sodom and Gomorrah, which were destroyed for their wickedness."[2]
