But what saith the scripture? Cast out the bond-woman and her son; for the son of the bond-woman shall not be heir with the son of the free-woman.

There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female; for ye are all one in Christ Jesus.

For it is written, Abraham had two sons, one by the bond-woman, another by the free-woman.

And he of the bond-woman was born after the flesh, but he of the free-woman by promise.

So then, brethren, we are not children of the bond-woman, but of the free.
