2. Sarah became pregnant. And she gave birth to a son for Abraham in his old age. Everything happened at the time God had said it would.
3. Abraham named his son Isaac. Sarah gave birth to this son of Abraham.
4. Abraham circumcised Isaac when he was eight days old as God had commanded.
5. Abraham was 100 years old when his son Isaac was born.
6. And Sarah said, “God has made me laugh. Everyone who hears about this will laugh with me.
7. No one thought that I would be able to have Abraham’s child. But I have given Abraham a son while he is old.”
8. Isaac grew and became old enough to eat food. At that time Abraham gave a great feast.
9. But Sarah saw Ishmael making fun of Isaac. (Ishmael was the son of Abraham by Hagar, Sarah’s Egyptian slave.)
10. So Sarah said to Abraham, “Throw out this slave woman and her son. When we die, our son Isaac will inherit everything we have. I don’t want her son to inherit any of our things.”
