Gen 17-18:15

The Sign of the Covenant 1When Abram was ninety-nine years old, the Lord appeared to Abram, and said to him, “I am God Almighty; walk before me, and be blameless.2And I will make my covenant between me and you, and will make you exceedingly numerous.”3Then Abram fell on his face; and God said to him,4“As for me, this is my covenant with you: You shall be the ancestor of a multitude of nations.5No longer shall your name be Abram, but your name shall be Abraham; for I have made you the ancestor of a multitude of nations.6I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you.7I will establish my covenant between me and you, and your offspring after you throughout their generations, for an everlasting covenant, to be God to you and to your offspring after you.8And I will give to you, and to your offspring after you, the land where you are now an alien, all the land of Canaan, for a perpetual holding; and I will be their God.”9God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations.10This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised.11You shall circumcise the flesh of your foreskins, and it shall be a sign of the covenant between me and you.12Throughout your generations every male among you shall be circumcised when he is eight days old, including the slave born in your house and the one bought with your money from any foreigner who is not of your offspring.13Both the slave born in your house and the one bought with your money must be circumcised. So shall my covenant be in your flesh an everlasting covenant.14Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”15God said to Abraham, “As for Sarai your wife, you shall not call her Sarai, but Sarah shall be her name.16I will bless her, and moreover I will give you a son by her. I will bless her, and she shall give rise to nations; kings of peoples shall come from her.”17Then Abraham fell on his face and laughed, and said to himself, “Can a child be born to a man who is a hundred years old? Can Sarah, who is ninety years old, bear a child?”18And Abraham said to God, “O that Ishmael might live in your sight!”19God said, “No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.20As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation.21But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.”22And when he had finished talking with him, God went up from Abraham.23Then Abraham took his son Ishmael and all the slaves 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.24Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin.25And his son Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin.26That very day Abraham and his son Ishmael were circumcised;27and all the men of his house, slaves born in the house and those bought with money from a foreigner, were circumcised with him.Chapter 18A Son Promised to Abraham and Sarah 1The Lord appeared to Abraham by the oaks of Mamre, as he sat at the entrance of his tent in the heat of the day.2He looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground.3He said, “My lord, if I find favor with you, do not pass by your servant.4Let a little water be brought, and wash your feet, and rest yourselves under the tree.5Let me bring a little bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.” So they said, “Do as you have said.”6And Abraham hastened into the tent to Sarah, and said, “Make ready quickly three measures of choice flour, knead it, and make cakes.”7Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it.8Then 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.9They said to him, “Where is your wife Sarah?” And he said, “There, in the tent.”10Then one said, “I will surely return to you in due season, and your wife Sarah shall have a son.” And Sarah was listening at the tent entrance behind him.11Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women.12So Sarah laughed to herself, saying, “After I have grown old, and my husband is old, shall I have pleasure?”13The Lord said to Abraham, “Why did Sarah laugh, and say, ‘Shall I indeed bear a child, now that I am old?’14Is anything too wonderful for the Lord? At the set time I will return to you, in due season, and Sarah shall have a son.”15But Sarah denied, saying, “I did not laugh”; for she was afraid. He said, “Oh yes, you did laugh.”
