Galatians 4:25-28 New King James Version (NKJV)

25. for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children—

26. but the Jerusalem above is free, which is the mother of us all.

27. For it is written:“Rejoice, O barren,You who do not bear!Break forth and shout,You who are not in labor!For the desolate has many more childrenThan she who has a husband.”

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