Genesis 21:11-13 New American Bible, Revised Edition (NABRE)

11. Abraham was greatly distressed because it concerned a son of his.

12. But God said to Abraham: Do not be distressed about the boy or about your slave woman. Obey Sarah, no matter what she asks of you; for it is through Isaac that descendants will bear your name.

13. As for the son of the slave woman, I will make a nation of him also, since he too is your offspring.
