3 And Abraham named their son Isaac.
4 Eight days after Isaac was born, Abraham circumcised him as God had commanded.
5 Abraham was 100 years old when Isaac was born.
6 And Sarah declared, “God has brought me laughter. All who hear about this will laugh with me.
7 Who would have said to Abraham that Sarah would nurse a baby? Yet I have given Abraham a son in his old age!”
8 When Isaac grew up and was about to be weaned, Abraham prepared a huge feast to celebrate the occasion.
9 But Sarah saw Ishmael—the son of Abraham and her Egyptian servant Hagar—making fun of her son, Isaac.
