'In Labor' in the Bible

Jerusalem, why are you now shouting so loudly? Has your king disappeared? Has your wise leader been destroyed? Is this why pain grips you as if you were a woman in labor?

Twist and strain, Daughter Zion, as if you were in labor! For you will leave the city and live in the open field. You will go to Babylon, but there you will be rescued. There the Lord will deliver you from the power of your enemies.

So the Lord will hand the people of Israel over to their enemies until the time when the woman in labor gives birth. Then the rest of the king's countrymen will return to be reunited with the people of Israel.
