Genesis 21:10-12

New Catholic Bible

¹⁰ She said to Abraham, “Send this slave and her son away, for the son of this slave must not be an heir together with my son Isaac.”

¹¹ This greatly distressed Abraham for he was concerned for his son. ¹² But God said to Abraham, “Do not let this matter with your son and the slave woman distress you. Listen to what Sarah tells you. Listen to her voice, for it is through Isaac that descendants will bear your name.
