Genesis 21:5-11 Catholic Public Domain Version (CPDV)

5. when he was one hundred years old. Indeed, at this stage of his father's life, Isaac was born.

6. And Sarah said: "God has brought laughter to me. Whoever will hear of it will laugh with me."

7. And again, she said: "Hearing this, who would believe Abraham, that Sarah breast-fed a son, to whom she gave birth, despite being elderly?"

8. And the boy grew and was weaned. And Abraham made a great feast on the day of his weaning.

9. And when Sarah had seen the son of Hagar the Egyptian playing with her son Isaac, she said to Abraham:

10. "Cast out this woman servant and her son. For the son of a woman servant will not be heir with my son Isaac."

11. Abraham took this grievously, for the sake of his son.
