11In the flesh of your private parts you are to undergo it, as a mark of the agreement between me and you.
12Every male among you, from one generation to another, is to undergo circumcision when he is eight days old, with every servant whose birth takes place in your house, or for whom you gave money to someone of another country, and not of your seed.
13He who comes to birth in your house and he who is made yours for a price, all are to undergo circumcision; so that my agreement may be marked in your flesh, an agreement for all time.
14And any male who does not undergo circumcision will be cut off from his people: my agreement has been broken by him.
15And God said, As for Sarai, your wife, from now her name will be not Sarai, but Sarah.
16And I will give her a blessing so that you will have a son by her: truly my blessing will be on her, and she will be the mother of nations: kings of peoples will be her offspring.
17Then Abraham went down on his face, and laughing, said in his heart, May a man a hundred years old have a child? will Sarah, at ninety years old, give birth?
