5 And Abraham was one hundred years old when his son Isaac was born unto him.
6 Then Sarah said, God has made me to laugh so that all that hear will laugh with me.
7 And she said, Who would have said unto Abraham, that Sarah should have given children suck? For I have born him a son in his old age.
8 And the child grew and was weaned, and Abraham made a great banquet the day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, whom she had born 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 grievous in Abraham’s sight because of his son.
