דברי הימים ב, פרק כ״ה, פסוק י״ב

The decisive battle concludes with a massive execution of enemy forces. The men of Judah captured ten thousand enemy fighters alive [מצודת ציון, ביאור שטיינזלץ]. After securing these prisoners, the Judeans carried out a mass execution by casting them off the top of a rock [ביאור שטיינזלץ]. The sheer force of the drop was entirely fatal, causing the stomachs of the captives to burst open upon impact with the ground below [מצודת דוד].

Reflecting on this harsh event and the chain of events that immediately follows, the Midrash connects the narrative to a concept from Proverbs. It compares the situation to a person who experiences a turbulent state of anger and laughter, ultimately finding no rest or peace [רש״י].
