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 Gentiles; 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 who is one hundred years old? and shall Sarah, who 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 (laughter); and I will confirm 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 shall bless 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 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 Then Abraham took Ishmael his son and all the servants 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 that same day as God had said unto him. 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 that same day Abraham was circumcised and Ishmael his son. 27 And all the men of his house, born in the house and bought with money from strangers, were circumcised with him.
1 And the LORD appeared unto him among the terebinth trees of Mamre; and he was sitting in the door of his tent in the heat of the day; 2 and he lifted up his eyes and looked, and, behold, 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 grace in thy sight, pass not away, I pray thee, from thy slave. 4 Let a little water, I pray you, be brought and wash your feet and rest yourselves under a tree; 5 and I will bring a morsel of bread and comfort your hearts; after that ye shall pass on because for this ye are come to your slave. 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 bread baked under the ashes. 7 And Abraham ran unto the herd and brought a calf tender and good and gave it unto a young man; 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 unto him, Where is Sarah thy wife? And he said, Here, in the tent. 10 Then he said, I will certainly return unto thee according to the time of life; and, behold, 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 Then the LORD said unto Abraham, Why did Sarah laugh, saying, Shall I of a surety bear a child when I 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. 15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, No, but thou didst 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 the LORD said, Shall I hide from Abraham that thing which I do, 18 seeing that Abraham shall surely become a great and mighty nation and that all the Gentiles of the earth shall be blessed in him? 19 For I know him, that he will command his sons and his household after him, and they shall keep the way of the LORD, to do righteousness and judgment, that the LORD may bring upon Abraham that which he has spoken of him. 20 And the 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 is come unto me; and if not, I will know.
