Genesis 21:11-13

Revised Standard Version

¹¹ And the thing was very displeasing to Abraham on account of his son. ¹² But God said to Abraham, “Be not displeased because of the lad and because of your slave woman; whatever Sarah says to you, do as she tells you, for through Isaac shall your descendants be named. ¹³ And I will make a nation of the son of the slave woman also, because he is your offspring.”
