6And Sarah said, God has given me cause for laughing, and everyone who has news of it will be laughing with me.
7And she said, Who would have said to Abraham that Sarah would have a child at her breast? for see, I have given him a son now when he is old.
8And when the child was old enough to be taken from the breast, Abraham made a great feast.
9And Sarah saw the son of Hagar the Egyptian playing with Isaac.
10So she said to Abraham, Send away that woman and her son: for the son of that woman is not to have a part in the heritage with my son Isaac.
11And this was a great grief to Abraham because of his son.
12But God said, Let it not be a grief to you because of the boy and Hagar his mother; give ear to whatever Sarah says to you, because it is from Isaac that your seed will take its name.
