Genesis 21:10-12

New Century Version

¹⁰ So Sarah said to Abraham, “Throw out this slave woman and her son. Her son should not inherit anything; my son Isaac should receive it all.”

¹¹ This troubled Abraham very much because Ishmael was also his son. ¹² But God said to Abraham, “Don’t be troubled about the boy and the slave woman. Do whatever Sarah tells you. The descendants I promised you will be from Isaac.
