Galatians 4:28-31

Etheridge(i) 28 BUT we, my brethren, as Ishak, are the children of promise. 29 And as then he who was born of the flesh persecuted him who was after the Spirit, so also now. 30 But what saith the scripture? Cast out the bondmaid and her son; for the son of the bondmaid shall not inherit with the son of the free. 31 We therefore, my brethren, are not the children of the bondmaid, but the children of the free.
