Abraham
God changes Abram’s name to Abraham and Sarai’s name to Sarah and promises him a son, Genesis 17:1-27

Genesis 17:1 And when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect.
2 And I will make my covenant between me and thee, and will multiply thee exceedingly.
3 And Abram fell on his face: and God talked with him, saying,
4 As for me, behold, my covenant is with thee, and thou shalt be a father of many nations.
5 Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee.
6 And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee.
7 And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.
8 And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.
9 And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations.
10 This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
11 And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.
12 And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed.
13 He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant.
14 And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.
15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.
16 And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her.
17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?
18 And Abraham said unto God, O that Ishmael might live before thee!
19 And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
20 And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.
21 But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.
22 And he left off talking with him, and God went up from Abraham.
23 And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham’s house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.
24 And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin.
25 And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin.
26 In the selfsame day was Abraham circumcised, and Ishmael his son.
27 And all the men of his house, born in the house, and bought with money of the stranger, were circumcised with him.
The Genealogy from Shem to Abraham, Genesis 9:18-19, Genesis 11:10-32

Genesis 9:18 And the sons of Noah, that went forth of the ark, were Shem, and Ham, and Japheth: and Ham is the father of Canaan.
19 These are the three sons of Noah: and of them was the whole earth overspread.

Genesis 11:10 These are the generations of Shem: Shem was an hundred years old, and begat Arphaxad two years after the flood:
11 And Shem lived after he begat Arphaxad five hundred years, and begat sons and daughters.
12 And Arphaxad lived five and thirty years, and begat Salah:
13 And Arphaxad lived after he begat Salah four hundred and three years, and begat sons and daughters.
14 And Salah lived thirty years, and begat Eber:
15 And Salah lived after he begat Eber four hundred and three years, and begat sons and daughters.
16 And Eber lived four and thirty years, and begat Peleg:
17 And Eber lived after he begat Peleg four hundred and thirty years, and begat sons and daughters.
18 And Peleg lived thirty years, and begat Reu:
19 And Peleg lived after he begat Reu two hundred and nine years, and begat sons and daughters.
20 And Reu lived two and thirty years, and begat Serug:
21 And Reu lived after he begat Serug two hundred and seven years, and begat sons and daughters.
22 And Serug lived thirty years, and begat Nahor:
23 And Serug lived after he begat Nahor two hundred years, and begat sons and daughters.
24 And Nahor lived nine and twenty years, and begat Terah:
25 And Nahor lived after he begat Terah an hundred and nineteen years, and begat sons and daughters.
26 And Terah lived seventy years, and begat Abram, Nahor, and Haran.
27 Now these are the generations of Terah: Terah begat Abram, Nahor, and Haran; and Haran begat Lot.
28 And Haran died before his father Terah in the land of his nativity, in Ur of the Chaldees.
29 And Abram and Nahor took them wives: the name of Abram’s wife was Sarai; and the name of Nahor’s wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah.
30 But Sarai was barren; she had no child.
31 And Terah took Abram his son, and Lot the son of Haran his son’s son, and Sarai his daughter in law, his son Abram’s wife; and they went forth with them from Ur of the Chaldees, to go into the land of Canaan; and they came unto Haran, and dwelt there.
32 And the days of Terah were two hundred and five years: and Terah died in Haran.
Abraham and Abimelech make a covenant
Genesis 21:22 And it came to pass at that time, that Abimelech and Phichol the chief captain of his host spake unto Abraham, saying, God is with thee in all that thou doest:
23 Now therefore swear unto me here by God that thou wilt not deal falsely with me, nor with my son, nor with my son’s son: but according to the kindness that I have done unto thee, thou shalt do unto me, and to the land wherein thou hast sojourned.
24 And Abraham said, I will swear.
25 And Abraham reproved Abimelech because of a well of water, which Abimelech’s servants had violently taken away.
26 And Abimelech said, I wot not who hath done this thing; neither didst thou tell me, neither yet heard I of it, but to day.
27 And Abraham took sheep and oxen, and gave them unto Abimelech; and both of them made a covenant.
28 And Abraham set seven ewe lambs of the flock by themselves.
29 And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?
30 And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.
31 Wherefore he called that place Beersheba; because there they sware both of them.
32 Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines.
33 And Abraham planted a grove in Beersheba, and called there on the name of the Lord, the everlasting God.
34 And Abraham sojourned in the Philistines’ land many days.
