Isaiah 37:3

And they said unto him, Thus saith Hezekiah, This day is a day of trouble, of great affliction, and of rebuke, the king recognizing here a reproof of the Lord on account of the sins of his people, and of blasphemy, namely, of the blasphemous utterances of Rabshakeh; for the children are come to the birth, and there is not strength to bring forth, the mother's labor being inadequate to complete the birth, the reference being to the situation in the nation, which was threatened with destruction on account of its own weakness.
