13. And my covenant shall be in your flesh for a perpetual covenant.
14. The male, whose dash of his foreskin shall not be circumcised, that soul shall be destroyed out of his people: because he hath broken my covenant.
15. God said also to Abraham: Sarai thy wife thou shalt not call Sarai, but Sara.
16. And I will bless her, and of her I will give thee a son, whom I will bless, and he shell become nations, and kings of people shall spring from him.
17. Abraham fell upon his face, and laughed, saying in his heart: Shall a son, thinkest thou, be born to him that is a hundred years old? and shall Sara that is ninety years old bring forth?
18. And he said to God: O that Ismael may live before thee.
19. And God said to Abraham: Sara thy wife shall bear thee a son, and thou shalt call his name Isaac, and I will establish my covenant with him for a perpetual covenant, and with his seed after him.
20. And as for Ismael I have also heard thee. Behold, I will bless him, and increase, and multiply him exceedingly: he shall beget twelve chiefs, and I will make him a great nation.
