Galatians 4:30 ASV

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

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

³⁰  Howbeit what saith the scripture? Cast out the handmaid and her son: for the son of the handmaid shall not inherit with the son of the freewoman.

³¹  Wherefore, brethren, we are not children of a handmaid, but of the freewoman.
