Galatians 4:30 WBT

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

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

³⁰  Nevertheless, 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.

³¹  So then, brethren, we are not children of the bond-woman, but of the free.
