But God said to Abraham, “Don’t be upset about the boy and your slave. Listen to what Sarah says because through Isaac your descendants will carry on your name.
God replied, “No! Your wife Sarah will give you a son, and you will name him Isaac [He Laughs]. I will make an everlasting promise to him and his descendants.
From the beginning I revealed the end. From long ago I told you things that had not yet happened, saying, “My plan will stand, and I’ll do everything I intended to do.”
But what does Scripture say? “Get rid of the slave woman and her son, because the son of the slave woman must never share the inheritance with the son of the free woman.”
