'Labor' in the Bible

So then, why do you shout a loud shout? Is there no king in you? Has your counselor perished that pangs like a woman in labor have seized you?

Writhe and groan, O daughter of Zion, like a woman in labor. For now you will go forth from the city, and you will camp in the field; you will go to Babylon. There you will be rescued; there Yahweh will redeem you from the hand of your enemies.
