writhing pain: the doubling-over agony of childbirth, used above all for the terror that grips people when God's judgment closes in
This is the noun for pain that bends a body double. Its home picture is childbirth: pain that arrives in waves, cannot be reasoned with, and leaves the person feeling it no choice but to cry out. The verb behind it (חוּל) describes the twisting itself, and it stretches as far as whirling and dancing; this noun only ever names the pain.
Jeremiah sets it inside a full scene of panic twice over, and the pattern is worth seeing whole:
- a report arrives that an enemy army is coming
- the hands of everyone who hears it go slack
- distress takes hold of them (צָרָה)
- and then this anguish grips them, like a woman in labor
The closing comparison, anguish like a woman in labor, comes back in Psalm 48:6, Jeremiah 22:23, and Micah 4:9. What the comparison is about is not weakness but helplessness. Nations that were sure of themselves are reduced to someone who cannot stop what is happening to her: the peoples who hear what God did at the sea (Exodus 15:14), the kings who take one look at Zion and run (Psalm 48:6), the king of Babylon when the news reaches him (Jeremiah 50:43). Micah 4:9 then turns the image around and finds hope in it, since labor pain is pain with something waiting on the other side of it.
Job uses a slightly longer form of the same word for his own suffering (Job 6:10): pain that shows no mercy and will not ease off. There no army is coming and nothing is being born. It is simply what he has to live inside.
