6 And Sarah said, God has made me to laugh; all who hear will laugh with me.
7 And she said, Who would have said to Abraham that Sarah would nurse children at the breast? For I have borne him a son in his old age! [Heb. 11:12.]
8 And the child grew and was weaned, and Abraham made a great feast the same day that Isaac was weaned.
9 Now Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking [Isaac].
10 Therefore she said to Abraham, Cast out this bondwoman and her son, for the son of this bondwoman shall not be an heir with my son Isaac. [Gal. 4:28-31.]
11 And the thing was very grievous (serious, evil) in Abraham's sight on account of his son [Ishmael].
12 God said to Abraham, Do not let it seem grievous and evil to you because of the youth and your bondwoman; in all that Sarah has said to you, do what she asks, for in Isaac shall your posterity be called. [Rom. 9:7.]
