Galatians 4:28-30

King James Version

²⁸ Now we, brethren, as Isaac was, are the children of promise.

²⁹ But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.

³⁰ Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.
