And God saith unto Abraham, `And thou dost keep My covenant, thou and thy seed after thee, to their generations;
this [is] My covenant which ye keep between Me and you, and thy seed after thee: Every male of you [is] to be circumcised;
and ye have circumcised the flesh of your foreskin, and it hath become a token of a covenant between Me and you.
`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;
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;
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.'
And God saith unto Abraham, `Sarai thy wife -- thou dost not call her name Sarai, for Sarah [is] her name;
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.'
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?'
And Abraham saith unto God, `O that Ishmael may live before Thee;'
and God saith, `Sarah thy wife is certainly bearing a son to thee, and thou hast called his name Isaac, and I have established My covenant with him, for a covenant age-during, to his seed after him.
