Genesis 17:15-Genesis 18:21 - Isaac's Birth Promised
15 And God said to Abraham, As for Sarai thy wife, thou shall not call her name Sarai, but her name shall be Sarah. 16 And I will bless her. And moreover I will give thee a son by her. Yea, I will bless her, and she shall be [a mother of] nations; kings of peoples shall be by her.
17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born to him who is a hundred years old? And shall Sarah, who is ninety years old, bear? 18 And Abraham said to God, Oh that Ishmael might live before thee!
19 And God said, No, but Sarah thy wife shall bear thee a son, and thou shall 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. He shall beget twelve princes, and I will make him a great nation. 21 But I will establish my covenant with Isaac, whom Sarah shall bear to 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 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 selfsame day, as God had 24 And Abraham was ninety-nine years old 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 Abraham was circumcised, and Ishmael his son. 27 And all the men of his house, those born in the house, and those bought with money from a foreigner, were circumcised with him.
1 And LORD appeared to 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 by 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, inasmuch as ye came to your servant. And they said, Do so as thou have said.
6 And Abraham hastened into the tent to Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes. 7 And Abraham ran to the herd, and fetched a calf tender and good, and gave it to the servant. And he hastened 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 ate.
9 And they said to him, Where is Sarah thy wife? And he said, Behold, in the tent.
10 And he said, I will certainly return to thee when the season comes 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 have become old shall I have pleasure, my lord also being old?
13 And LORD said to Abraham, Why did Sarah laugh, saying, Shall I who am old certainly bear a child? 14 Is anything too hard for LORD? At the set time I will return to thee, when the season comes round, and Sarah shall have a son.
15 Then Sarah denied, saying, I did not laugh, for she was afraid. And he said, No, but thou did laugh.
16 And the men rose up from there, and looked toward Sodom. And Abraham went with them to bring them on the way. 17 And LORD said, Shall I hide from Abraham that which I do, 18 since Abraham shall 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 LORD, to do righteousness and justice, to the end that LORD may bring upon Abraham that which he has spoke 20 And LORD 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 comes to me. And if not, I will know.
