28 My brothers, you are God’s children because of his promise, as Isaac was then.
29 The son who was born in the normal way treated the other son badly. It is the same today.
30 But what does the Scripture say? “Throw out the slave woman and her son! The son of the free woman will receive everything his father has. But the son of the slave woman will receive nothing.”
31 So, my brothers, we are not children of the slave woman. We are children of the free woman.
