Isaac’s Birth Promised

15 And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah4 shall be her name. 16 I will bless her, and moreover, I will cgive5 you a son by her. I will bless her, and dshe shall become nations; kings of peoples shall come from her.” 17 Then Abraham efell on his face fand laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” 18 And Abraham said to God, “Oh that Ishmael might live before you!” 19 God said, “No, but gSarah your wife shall bear you a son, and you shall call his name hIsaac.6 I will establish my covenant with him as an everlasting covenant for his offspring after him. 20 As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and imultiply him greatly. He jshall father twelve princes, and kI will make him into a great nation. 21 But lI will establish my covenant with Isaac, mwhom Sarah shall bear to you at this time next year.”

22 When he had finished talking with him, nGod went up from Abraham. 23 Then Abraham took Ishmael his son and all those born in his house or bought with his money, every male among the men of Abraham’s house, and he circumcised the flesh of their foreskins that very day, as God had said to him. 24 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 That very day Abraham and his son Ishmael were circumcised. 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.

18 And the Lord appeared to him by the ooaks1 of Mamre, as he sat at the door of his tent in the heat of the day. 2 He lifted up his eyes and looked, and behold, three men were standing in front of him. pWhen he saw them, he ran from the tent door to meet them and bowed himself to the earth 3 and said, “O Lord,2 if I have found favor in your sight, do not pass by your servant. 4 Let a qlittle water be brought, and wash your feet, and rest yourselves under the tree, 5 while I bring a morsel of bread, that ryou may refresh yourselves, and after that you may pass on—ssince you have come to your servant.” So they said, “Do as you have said.” 6 And Abraham went quickly into the tent to Sarah and said, “Quick! Three seahs3 of fine flour! Knead it, and make cakes.” 7 And Abraham ran to the herd and took a calf, tender and good, and gave it to a young man, who prepared it quickly. 8 Then he took curds and milk and the calf that he had prepared, and set it before them. And he stood by them under the tree while they ate.

9 They said to him, “Where is Sarah your wife?” And he said, “She is tin the tent.” 10 The Lord said, “I will surely return to you uabout this time next year, and vSarah your wife shall have a son.” And Sarah was listening at the tent door behind him. 11 Now wAbraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. 12 xSo Sarah laughed to herself, saying, y“After I am worn out, and zmy lord is old, shall I have pleasure?” 13 The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ 14 aIs anything too hard4 for the Lord? bAt the appointed time I will return to you, about this time next year, and Sarah shall have a son.” 15 But Sarah denied it,5 saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”
