Genesis 21:1-13

1The Lord kept his word and did for Sarah exactly what he had promised.

2She became pregnant, and she gave birth to a son for Abraham in his old age. This happened at just the time God had said it would.

3And Abraham named their son Isaac.

4Eight days after Isaac was born, Abraham circumcised him as God had commanded.

5Abraham was 100 years old when Isaac was born.

6And Sarah declared, “God has brought me laughter. All who hear about this will laugh with me.

7Who would have said to Abraham that Sarah would nurse a baby? Yet I have given Abraham a son in his old age!”

8When Isaac grew up and was about to be weaned, Abraham prepared a huge feast to celebrate the occasion.

9But Sarah saw Ishmael—the son of Abraham and her Egyptian servant Hagar—making fun of her son, Isaac.

10So she turned to Abraham and demanded, “Get rid of that slave woman and her son. He is not going to share the inheritance with my son, Isaac. I won’t have it!”

11This upset Abraham very much because Ishmael was his son.

12But God told Abraham, “Do not be upset over the boy and your servant. Do whatever Sarah tells you, for Isaac is the son through whom your descendants will be counted.

13But I will also make a nation of the descendants of Hagar’s son because he is your son, too.”
