Genesis 21:10-12

Living Bible

¹⁰ she turned upon Abraham and demanded, “Get rid of that slave girl and her son. He is not going to share your property with my son. I won’t have it.”

¹¹ This upset Abraham very much, for after all, Ishmael too was his son.

¹² But God told Abraham, “Don’t be upset over the boy or your slave-girl wife; do as Sarah says, for Isaac is the son through whom my promise will be fulfilled.
