1After these things, God tested Abraham, and said to him, “Abraham!”
He said, “Here I am.”
2He said, “Now take your son, your only son, Isaac, whom you love, and go into the land of Moriah. Offer him there as a burnt offering on one of the mountains which I will tell you of.”
3Abraham rose early in the morning, and saddled his donkey; and took two of his young men with him, and Isaac his son. He split the wood for the burnt offering, and rose up, and went to the place of which God had told him. 4On the third day Abraham lifted up his eyes, and saw the place far off. 5Abraham said to his young men, “Stay here with the donkey. The boy and I will go over there. We will worship, and come back to you.” 6Abraham took the wood of the burnt offering and laid it on Isaac his son. He took in his hand the fire and the knife. They both went together. 7Isaac spoke to Abraham his father, and said, “My father?”
He said, “Here I am, my son.”
He said, “Here is the fire and the wood, but where is the lamb for a burnt offering?”
8Abraham said, “God will provide himself the lamb for a burnt offering, my son.” So they both went together. 9They came to the place which God had told him of. Abraham built the altar there, and laid the wood in order, bound Isaac his son, and laid him on the altar, on the wood. 10Abraham stretched out his hand, and took the knife to kill his son.
11Yahweh’s angel called to him out of the sky, and said, “Abraham, Abraham!”
He said, “Here I am.”
12He said, “Don’t lay your hand on the boy or do anything to him. For now I know that you fear God, since you have not withheld your son, your only son, from me.”
13Abraham lifted up his eyes, and looked, and saw that behind him was a ram caught in the thicket by his horns. Abraham went and took the ram, and offered him up for a burnt offering instead of his son. 14Abraham called the name of that place “Yahweh Will Provide”. As it is said to this day, “On Yahweh’s mountain, it will be provided.”
15Yahweh’s angel called to Abraham a second time out of the sky, 16and said, “‘I have sworn by myself,’ says Yahweh, ‘because you have done this thing, and have not withheld your son, your only son, 17that I will bless you greatly, and I will multiply your offspring greatly like the stars of the heavens, and like the sand which is on the seashore. Your offspring will possess the gate of his enemies. 18All the nations of the earth will be blessed by your offspring, because you have obeyed my voice.’”
19So Abraham returned to his young men, and they rose up and went together to Beersheba. Abraham lived at Beersheba.
20After these things, Abraham was told, “Behold, Milcah, she also has borne children to your brother Nahor: 21Uz his firstborn, Buz his brother, Kemuel the father of Aram, 22Chesed, Hazo, Pildash, Jidlaph, and Bethuel.” 23Bethuel became the father of Rebekah. These eight Milcah bore to Nahor, Abraham’s brother. 24His concubine, whose name was Reumah, also bore Tebah, Gaham, Tahash, and Maacah.
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]
