4:24. Which things are said by an allegory. For these are the two testaments. The one from Mount Sina, engendering unto bondage, which is Agar.
4:25. For Sina is a mountain in Arabia, which hath affinity to that Jerusalem which now is: and is in bondage with her children.
4:26. But that Jerusalem which is above is free: which is our mother.
4:27. For it is written: Rejoice, thou barren, that bearest not: break forth and cry thou that travailest not: for many are the children of the desolate, more than of her that hath a husband.
4:28. Now we, brethren, as Isaac was, are the children of promise.
4:29. But as then he that was born according to the flesh persecuted him that was after the spirit: so also it is now.
4:30. But 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 free woman.
4:31. So then, brethren, we are not the children of the bondwoman but of the free: by the freedom wherewith Christ has made us free.
Galatians Chapter 5
He exhorts them to stand to their Christian liberty. Of the fruits of the flesh and of the spirit.
