[1] After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.

[2] And Abram said, Lord GOD, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?

[3] And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.

[4] And, behold, the word of the LORD came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.

[5] And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.

[6] And he believed in the LORD; and he counted it to him for righteousness.

17:1-8,15-19

[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.

[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.

18:1- 5,9-14

[1] And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;

[2] And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,

[3] And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:

[4] Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:

[5] And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.

[9] And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent.

[10] And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him.

[11] Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women.

[12] Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

[13] And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?

[14] Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

21:1-3

[1] And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.

[2] For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.

[3] And Abraham called the name of his son that was born unto him, whom Sarah bare to him, Isaac.
