Galatians 4:27-31

27For it is written, “1Rejoice, barren woman who does not bear; Break forth and shout, you who are not in labor; For more numerous are the children of the desolate Than of the one who has a husband.” 28And you brethren, 2like Isaac, are 3children of promise. 29But as at that time 4he who was born according to the flesh 5persecuted him who was born according to the Spirit, 6so it is now also. 30But what does the Scripture say? “7Cast out the bondwoman and her son, For 8the son of the bondwoman shall not be an heir with the son of the free woman.” 31So then, brethren, we are not children of a bondwoman, 9but of the free woman.
