9. And when Sara had seen the son of Agar the Egyptian playing with Isaac her son, she said to Abraham:
10. Cast out this bondwoman, and her son: for the son of the bondwoman shall not be heir with my son Isaac.
11. Abraham took this grievously for his son.
12. And God said to him: Let it not seem grievous to thee for the boy, and for thy bondwoman: in all that Sara hath said to thee, hearken to her voice: for in Isaac shall thy seed be called.
13. But I will make the son also of the bondwoman a great nation, because he is thy seed.
