Samson's final moments reach a dramatic peak of self-sacrifice and revenge. Knowing his end is near, he chooses to take down the Philistine leadership in one final blow. He expresses a complete readiness to die alongside his enemies. His desire for their destruction is so intense that he willingly accepts his own death, as long as it ensures they die with him [מצודת דוד, ביאור שטיינזלץ].
In his last action, Samson uses his hands to push and bend the two main pillars of the building with great strength [מצודת דוד, ביאור שטיינזלץ]. Because these pillars are the central support for the structure, their collapse causes the entire roof to cave in on everyone inside [ביאור שטיינזלץ].
The death toll from this event is massive [מצודת דוד]. With this single strike, Samson successfully kills all the important Philistine figures and leaders, ultimately causing more deaths in his final moment than he did throughout his entire life [ביאור שטיינזלץ].
