1 When Abram was ninety-nine years old, the LORD appeared to him and said, "I am God Almighty. Walk before me and be blameless,
2 so that I may set my covenant between me and you and multiply you beyond measure."
3 Abram fell on his face, and God spoke with him:
4 "As for me, here is my covenant with you: you will be the father of a host of nations.
5 Your name will no longer be called Abram; your name will be Abraham, because I have made you the father of a host of nations.
6 I will make you fruitful beyond measure; I will make nations out of you, and kings will come from you.
7 I will establish my covenant between me and you and your seed after you, through their generations, as an everlasting covenant, to be God to you and to your seed after you.
8 To you and to your seed after you I will give the land where you are now a stranger, the whole land of Canaan, as a possession forever; and I will be their God."
9 God said further to Abraham, "And you, you must keep my covenant, you and your seed after you through their generations.
10 This is my covenant between me and you and your seed after you, which you are to keep: every male among you is to be circumcised.
11 You are to circumcise the flesh of your foreskin, and that will be the sign of the covenant between me and you.
12 At eight days old every male among you is to be circumcised, through your generations, the one born in the house and the one bought with money from any foreigner who is not of your seed.
13 Both the one born in your house and the one bought with your money must be circumcised; so my covenant will be in your flesh as an everlasting covenant.
14 An uncircumcised male, whose foreskin flesh has not been circumcised—that soul will be cut off from his people; he has broken my covenant."
15 God also said to Abraham, "Sarai your wife—you are not to call her Sarai; her name is to be Sarah.
16 I will bless her, and from her I will give you a son as well. I will bless her, and she will become nations; kings of peoples will come from her."
17 Abraham fell on his face and laughed, saying to himself, "Will a son be born to a man a hundred years old? Will Sarah, at ninety years, give birth?"
18 And Abraham said to God, "If only Ishmael might live in your presence!"
19 God said, "Not so; your wife Sarah will bear you a son, and you will name him Isaac. I will establish my covenant with him as an everlasting covenant for his seed after him.
20 And concerning Ishmael, I have heard you. I have indeed blessed him; I will make him fruitful and multiply him beyond measure. He will become the father of twelve chieftains, and I will make him a great nation.
21 But my covenant I will establish with Isaac, whom Sarah will bear to you at this season next year."
22 Having finished speaking with him, God went up from Abraham.
23 Then Abraham took his son Ishmael and all who were born in his house and all who were bought with his money, every male among the men of Abraham's household, and he circumcised the flesh of their foreskins on that very day, as God had told him.
24 Abraham was ninety-nine years old at the circumcision of the flesh of his foreskin.
25 His son Ishmael was thirteen years old at the circumcision of the flesh of his foreskin.
26 On that very day Abraham and his son Ishmael were circumcised.
27 All the men of his household, those born in the house and those bought with money from foreigners, were circumcised along with him.
