Genesis 17:15-Genesis 18:21 - Isaac's Birth Promised

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 moreover I will give thee a son of her: yea, I will bless her, and she shall be a mother of nations; kings of peoples 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 a hundred years old? and shall Sarah, that is ninety years old, bear? 18 And Abraham said unto God, Oh that Ishmael might live before thee!

19 And God said, Nay, but Sarah thy wife shall bear thee a son; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant for 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, whom 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, those born in the house, and those bought with money of a foreigner, were circumcised with him.

1 And Jehovah appeared unto him by the oaks of Mamre, as he sat in the tent door in the heat of the day; 2 and he lifted up his eyes and looked, and, lo, three men stood over against him: and when he saw them, he ran to meet them from the tent door, and bowed himself to the earth, 3 and said, My lord, if now I have found favor in thy sight, pass not away, I pray thee, from thy servant: 4 let now a little water be fetched, and wash your feet, and rest yourselves under the tree: 5 and I will fetch a morsel of bread, and strengthen ye your heart; after that ye shall pass on: forasmuch as ye are come to your servant. And they said, So do, as thou hast said.

6 And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes. 7 And Abraham ran unto the herd, and fetched a calf tender and good, and gave it unto the servant; and he hasted to dress it. 8 And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.

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 when the season cometh round; and, lo, Sarah thy wife shall have a son. And Sarah heard in the tent door, which was behind him.

11 Now Abraham and Sarah were old, and well stricken in age; it had ceased to be with Sarah after the manner of women. 12 And Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

13 And Jehovah said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, who am old? 14 Is anything too hard for Jehovah? At the set time I will return unto thee, when the season cometh round, and Sarah shall have a son.

15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

16 And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way. 17 And Jehovah said, Shall I hide from Abraham that which I do; 18 seeing that Abraham had surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? 19 For I have known him, to the end that he may command his children and his household after him, that they may keep the way of Jehovah, to do righteousness and justice; to the end that Jehovah may bring upon Abraham that which he hath spoken of him. 20 And Jehovah said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous; 21 I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.
