541 "Sing, barren woman, who has never had a baby. Fill the air with song, you who've never experienced childbirth! You're ending up with far more children than all those childbearing women." God says so!
541 Let your voice be loud in song, O woman without children; make melody and sounds of joy, you who did not give birth: for the children of her who had no husband are more than those of the married wife, says the Lord.
