1When Abram was ninety-nine years old, Yahweh appeared to Abram and said to him, “I am God Almighty. Walk before me and be blameless. 2I will make my covenant between me and you, and will multiply you exceedingly.”
3Abram fell on his face. God talked with him, saying, 4“As for me, behold, my covenant is with you. You will be the father of a multitude of nations. 5Your name will no more be called Abram, but your name will be Abraham; for I have made you the father of a multitude of nations. 6I will make you exceedingly fruitful, and I will make nations of you. Kings will come out of you. 7I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be a God to you and to your offspring after you. 8I will give to you, and to your offspring after you, the land where you are traveling, all the land of Canaan, for an everlasting possession. I will be their God.”
9God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10This is my covenant, which you shall keep, between me and you and your offspring after you. Every male among you shall be circumcised. 11You shall be circumcised in the flesh of your foreskin. It will be a token of the covenant between me and you. 12He who is eight days old shall be circumcised among you, every male throughout your generations, he who is born in the house, or bought with money from any foreigner who is not of your offspring. 13He who is born in your house, and he who is bought with your money, must be circumcised. My covenant shall be in your flesh for an everlasting covenant. 14The uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people. He has broken my covenant.”
15God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but her name shall be Sarah. 16I will bless her, and moreover I will give you a son by her. Yes, I will bless her, and she will be a mother of nations. Kings of peoples will come from her.”
17Then Abraham fell on his face, and laughed, and said in his heart, “Will a child be born to him who is one hundred years old? Will Sarah, who is ninety years old, give birth?” 18Abraham said to God, “Oh that Ishmael might live before you!”
19God said, “No, but Sarah, your wife, will bear you a son. You shall call his name Isaac. I will establish my covenant with him for an everlasting covenant for his offspring after him. 20As for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He will become the father of twelve princes, and I will make him a great nation. 21But I will establish my covenant with Isaac, whom Sarah will bear to you at this set time next year.”
22When he finished talking with him, God went up from Abraham. 23Abraham took Ishmael his son, all who were born in his house, and all who were bought with his money: every male among the men of Abraham’s house, and circumcised the flesh of their foreskin in the same day, as God had said to him. 24Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. 25Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin. 26In the same day both Abraham and Ishmael, his son, were circumcised. 27All the men of his house, those born in the house, and those bought with money from a foreigner, were circumcised with him.
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]
