Genesis 17:15-Genesis 18:21 - Isaac's Birth Promised
15 And God said to Abraham, "[as for] Sarai your wife, you shall not call her name Sarai, for Sarah [shall be] her name. 16 And I will bless her; moreover, I give to you from her a son. And I will bless her, and {she shall give rise to nations}. Kings of peoples shall come from her."
17 And Abraham fell upon his face and laughed. And he said in his heart, "{Can a child be born to a man a hundred years old}, or {can Sarah bear a child at ninety}?" 18 And Abraham said to God, "Oh that Ishmael might live before you!"
19 And God said, "No, but Sarah your wife shall bear a son for you, and you shall call his name Isaac. And I will establish my covenant with him as an everlasting covenant to his offspring after him. 20 And [as for] Ishmael, I have heard you. Behold, I will bless him and I will make him fruitful, and I will multiply him {exceedingly}. He shall father twelve princes, and I will make him a great nation. 21 But my covenant I will establish with Isaac, whom Sarah shall bear to you at this appointed time next year." 22 When he finished speaking with him, God went up from Abraham.
23 And Abraham took Ishmael his son and all who were born of his house, and all [those] acquired by his money, every male among the men of Abraham's house, and he circumcised the flesh of their foreskin on the same day that God spoke with him. 24 Abraham [was] ninety-nine years old when he circumcised the flesh of his foreskin. 25 And Ishmael his son [was] thirteen years old when he circumcised the flesh of his foreskin. 26 Abraham and his son Ishmael [were] circumcised on the same day. 27 And all the men of his house, {those born in the house, and those acquired by money from a foreigner}, were circumcised with him.
1 And Yahweh appeared to him by the oaks of Mamre. And he was sitting in the doorway of the tent at the heat of the day. 2 And he lifted up his eyes and saw, and behold, three men were standing near him. And he saw [them] and ran from the doorway of the tent to meet them. And he bowed down to the ground. 3 And he said, "My lord, if I have found favor in your eyes do not pass by your servant. 4 Let a little water be brought and wash your feet, and rest under the tree. 5 And let me bring a piece of bread, then refresh {yourselves}. Afterward you can pass on, {once} you have passed by with your servant." Then they said, "Do so as you have said."
6 Then Abraham hastened into the tent to Sarah, and he said, "Quickly--make three seahs of fine flour for kneading and make bread cakes!" 7 And Abraham ran to the cattle and took a {calf}, tender and good, and gave it to the servant, and he made haste to prepare it. 8 Then he took curds and milk, and the calf which he prepared, and set [it] before them. And he was standing by them under the tree while they ate.
9 And they said to him, "Where [is] Sarah your wife?" And he said, "Here, in the tent."
10 And he said, "I will certainly return to you {in the spring}, and look, Sarah your wife [will have] a son." Now Sarah [was] listening at the doorway of the tent, and which [was] behind him.
11 Now Abraham and Sarah [were] old, {advanced in age}; {the way of women} had ceased to be for Sarah. 12 So Sarah laughed to herself saying, "After I am worn out and my husband is old, shall [this] pleasure be to me?"
13 Then Yahweh said to Abraham, "What [is] this [that] Sarah laughed, saying, 'Is it indeed true [that] I will bear a child, now [that] I have grown old?' 14 Is anything too difficult for Yahweh? At the appointed time I will return to you {in the spring} and Sarah [shall have] a son."
15 But Sarah denied [it], saying, "I did not laugh," because she was afraid. He said, "No, but you did laugh."
16 Then the men set out from there, and they looked down upon Sodom. And Abraham went with them {to send them on their way}. 17 Then Yahweh said, "Shall I conceal from Abraham what I [am going] to do? 18 Abraham will surely become a great and strong nation, and all the nations of the earth will be blessed on account of him. 19 For I have chosen him, that he will command his children and his household after him that they will keep the way of Yahweh, to do righteousness and justice, so that Yahweh may bring upon Abraham that which he said to him." 20 Then Yahweh said, "Because the outcry of Sodom and Gomorrah [is] great and because their sin [is] very {serious}, 21 I will go down and I will see. Have they done altogether according to its cry of distress [which] has come to me? If not, I will know."
