7 And she said, Who would have said unto Abraham, that Sarah should have nursed children? for I have borne him a son in his old age.
8 And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, whom she had borne unto Abraham, mocking.
10 Therefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
11 And the thing was very displeasing in Abraham's sight because of his son.
12 And God said unto Abraham,
13 And also of the son of the bondwoman will I make a nation, because he is your descendant.
