1. And the LORD visited Sarah as he had said, and the LORD did to Sarah as he had spoken.
2. For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him.
3. And Abraham called the name of his son that was born to him, whom Sarah bore to him, Isaac.
4. And Abraham circumcised his son Isaac, being eight days old, as God had commanded him.
5. And Abraham was a hundred years old, when his son Isaac was born to him.
6. And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7. And she said, Who would have said to Abraham, that Sarah shall nurse children? for I have borne him a son in his old age.
8. And the child grew, and was weaned: and Abraham made a great feast the day that Isaac was weaned.
9. And Sarah saw the son of Hagar the Egyptian, which she had borne to Abraham, mocking.
10. Wherefore, she said to Abraham, Cast out this bond-woman, and her son: for the son of this bond-woman shall not be heir with my son, even with Isaac.
11. And the thing was very grievous in Abraham's sight, because of his son.
12. And God said to Abraham, Let it not be grievous in thy sight, because of the lad, and because of thy bond-woman; in all that Sarah hath said to thee, hearken to her voice: for in Isaac shall thy seed be called.
