15 And this shall be my covenant which ye shall keep between me and thee and thy seed after thee; every man-child among you shall be circumcised.
16 And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.
17 And he that is eight days old shall be circumcised among you, every man-child in your generations;
18 He that is born in the house, or bought with money of any stranger, which is not of thy seed.
19 He that is born in thy house, and he that is bought with thy money, must needs be circumcised, and my covenant shall be in your flesh for an everlasting covenant.
20 And the uncircumcised man-child, whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people, he hath broken my covenant.
21 And God said unto Abraham, as for Sarai thy wife, thou shalt not call her name Sarai, but Sarah thou shalt call her name.
22 And I will bless her, and I will give thee a son of her; yea, I will bless her, and she shall be blessed, The mother of nations; kings and people shall be of her.
23 Then Abraham fell on his face and rejoiced, and said in his heart, There shall a child be born unto him that is an hundred years old, and Sarah that is ninety years old shall bear.
24 And Abraham said unto God, Oh that Ishmael might live uprightly before thee!
25 And God said, Sarah thy wife shall bare thee a son, and thou shalt call his name Isaac; and I will establish my covenant with him also, for an everlasting covenant with his seed after him.
