Isaiah 54:1, 6

“Shout for joy, O barren one, she who has not given birth; Break forth into joyful shouting and rejoice, she who has not gone into labor [with child]! For the [spiritual] sons of the desolate one will be more numerous Than the sons of the married woman,” says the LORD. [Gal 4:27]

“For the LORD has called you, Like a wife who has been abandoned, grieved in spirit, And like a wife [married] in her youth when she is [later] rejected and scorned,” Says your God.
