KJV:
Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for more are the children of the desolate than the children of the married wife, saith the LORD.
NASB:
"Shout for joy, O barren one, you who have borne no child; Break forth into joyful shouting and cry aloud, you who have not travailed; For the sons of the desolate one will be more numerous Than the sons of the married woman," says the LORD.
