4 And when his son Isaac was eight days old, Abraham made him undergo circumcision, as God had said to him.
5 Now Abraham was a hundred years old when the birth of Isaac took place.
6 And Sarah said, God has given me cause for laughing, and everyone who has news of it will be laughing with me.
7 And 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.
8 And when the child was old enough to be taken from the breast, Abraham made a great feast.
9 And Sarah saw the son of Hagar the Egyptian playing with Isaac.
10 So 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.
