Genesis 21

¹And the Lord came to Sarah as he had said and did to her as he had undertaken.

²And Sarah became with child, and gave Abraham a son when he was old, at the time named by God.

³And Abraham gave to his son, to whom Sarah had given birth, the name Isaac.

⁴And when his son Isaac was eight days old, Abraham made him undergo circumcision, as God had said to him.

⁵Now Abraham was a hundred years old when the birth of Isaac took place.

⁶And Sarah said, God has given me cause for laughing, and everyone who has news of it will be laughing with me.

⁷And she said, Who would have said to Abraham that Sarah would have a child at her breast? for see, I have given him a son now when he is old.

⁸And when the child was old enough to be taken from the breast, Abraham made a great feast.

⁹And Sarah saw the son of Hagar the Egyptian playing with Isaac.

¹⁰So she said to Abraham, Send away that woman and her son: for the son of that woman is not to have a part in the heritage with my son Isaac.

¹¹And this was a great grief to Abraham because of his son.

¹²But God said, Let it not be a grief to you because of the boy and Hagar his mother; give ear to whatever Sarah says to you, because it is from Isaac that your seed will take its name.

¹³And I will make a nation of the son of your servant-woman, because he is your seed.
