27 For it is written:
"Rejoice, O barren woman,
who bears no children;
break forth and cry aloud,
you who have never travailed;
because more are the children of the desolate woman
than of her who has a husband."4:27 Isaiah 54:1
28 Now you,4:28 WH, BYZ, and TR we brothers, like Isaac, are children of promise. 29 At that time, however, the son born by the flesh persecuted the son born by the Spirit. It is the same now.
