Genesis Chapter 17

1 When Abram was 99 years old, the Lord appeared to Abram and said to him, I am the Almighty God. Walk before me and be perfect.
2 I will make my covenant between me and you, and will multiply you exceedingly.
3 Abram fell on his face. And God talked with him saying,
4 As for me, behold, my covenant is with you, and you shall be a father of many nations.
5 Neither shall your name any more be called Abram, but your name shall be Abraham. For I have made you a father of many nations.
6 I will make you exceedingly fruitful, greatly so, and I will make nations of you, and kings shall come out of you.
7 I will establish my covenant between me and you and your descendants after you in their generations for an everlasting covenant, to be a God to you and to your descendants after you.
8 I will give the land to you in which you are a stranger, and to your descendants after you, all the land of Canaan, for an everlasting possession. And I will be their God.
9 God said to Abraham, And you shall keep my covenant, you and your descendants after you in their generations.
10 This is my covenant that you shall keep, between me and you and your descendants after you. Every male child among you shall be circumcised.
11 You shall circumcise the flesh of your foreskin. It shall be a token of the covenant between me and you.
12 A son after eight days shall be circumcised among you. Every male child in your generations. Those born in the house or bought with silver from any stranger who is not of your descendants.
13 Those born in your house and those bought with your silver must be circumcised. My covenant will be in your flesh for an everlasting covenant.
14 The uncircumcised male child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people for he has broken my covenant.
15 God said to Abraham, As for Sarai your wife, you shall not call her name Sarai, but her name shall be Sarah.
16 I will bless her and give you a son also. Yes, I will bless her and she will be a mother of nations, kings of people will come from her.
17 Abraham fell on his face and laughed and said in his heart, Shall a child be born to one who is 100 years old? Shall Sarah who is 90 years old give birth?
18 Abraham said to God, Oh that Ishmael might live before you.
19 God said, Sarah your wife will bear you a son indeed and you shall call his name Isaac. I will establish my covenant with him for an everlasting covenant and with his descendants after him.
20 As for Ishmael, I have heard you. Behold, I have blessed him and will make him fruitful and will multiply him exceedingly. He will father twelve princes and I will make him a great nation.
21 I will establish my covenant with Isaac whom Sarah will bear to you at a set time in the next year.
22 When He stopped talking with him, God went up from Abraham.
23 So Abraham took his son Ishmael and all who were born in his house and all who were bought with his silver. Every male among the men of Abraham's house. And he circumcised the flesh of their foreskins in the same day, as God said to him.
24 Abraham was 99 years old when he was circumcised in the flesh of his foreskin.
25 His son Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin.
26 In the same day Abraham and his son Ishmael were circumcised.
27 All the men of his house who were born in the house and bought with silver from a stranger were circumcised with him.
