In Context

12 'And a son of eight days is circumcised by you; every male to your generations, born in the house, or bought with money from any son of a stranger, who is not of thy seed;

13 he is certainly circumcised who is born in thine house, or bought with thy money; and My covenant hath become in your flesh a covenant age-during;

14 and an uncircumcised one, a male, the flesh of whose foreskin is not circumcised, even that person hath been cut off from his people; My covenant he hath broken.'

15 And God saith unto Abraham, 'Sarai thy wife — thou dost not call her name Sarai, for Sarah is her name;

16 and I have blessed her, and have also given to thee a son from her; and I have blessed her, and she hath become nations — kings of peoples are from her.'

17 And Abraham falleth upon his face, and laugheth, and saith in his heart, 'To the son of an hundred years is one born? or doth Sarah — daughter of ninety years — bear?'
