Genesis 21:1-13

1The Lord visited Sarah just as he had said he would and did for Sarah what he had promised.

2So Sarah became pregnant and bore Abraham a son in his old age at the appointed time that God had told him.

3Abraham named his son – whom Sarah bore to him – Isaac.

4When his son Isaac was eight days old, Abraham circumcised him just as God had commanded him to do.

5(Now Abraham was a hundred years old when his son Isaac was born to him.)

6Sarah said, “God has made me laugh. Everyone who hears about this will laugh with me.”

7She went on to say, “Who would have said to Abraham that Sarah would nurse children? Yet I have given birth to a son for him in his old age!”

8The child grew and was weaned. Abraham prepared a great feast on the day that Isaac was weaned.

9But Sarah noticed the son of Hagar the Egyptian – the son whom Hagar had borne to Abraham – mocking.

10So she said to Abraham, “Banish that slave woman and her son, for the son of that slave woman will not be an heir along with my son Isaac!”

11Sarah’s demand displeased Abraham greatly because Ishmael was his son.

12But God said to Abraham, “Do not be upset about the boy or your slave wife. Do all that Sarah is telling you because through Isaac your descendants will be counted.

13But I will also make the son of the slave wife into a great nation, for he is your descendant too.”
