2 And Sarah became with child, and gave Abraham a son when he was old, at the time named by God.
3 And Abraham gave to his son, to whom Sarah had given birth, the name Isaac.
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.
