But what says the Scripture? Cast out the servant-woman and her son; for the son of the servant woman shall not be an heir, with the son of the free.

For it is written, that Abraham had two sons, one by a servant woman, and the other by a free woman.

But he by the servant woman was born of the flesh, and he by the free woman, by the promise.

Wherefore, brothers, we are not children of the servant woman, but of the free.
