Genesis 21:11-13

New Revised Standard Version Catholic Edition

¹¹ The matter was very distressing to Abraham on account of his son. ¹² But God said to Abraham, “Do not be distressed because of the boy and because of your slave woman; whatever Sarah says to you, do as she tells you, for it is through Isaac that offspring shall be named for you. ¹³ As for the son of the slave woman, I will make a nation of him also, because he is your offspring.”
