The history of the Israelites, particularly during the era of the Judges, is defined by a repeating cycle of sin, punishment, a desperate cry to God, and divine salvation [ביאור שטיינזלץ, מלבי״ם]. Because of their actions, the Israelites were handed over to adversaries who brought severe distress and trouble upon them [מצודת ציון]. These oppressors were not necessarily enemies driven by a deep emotional hatred; rather, they caused suffering simply for their own personal gain and pleasure.
This dynamic of suffering and response was a continuous, habitual pattern throughout their history. Whenever the Israelites found themselves in deep distress, they would repeatedly cry out to God, and He would consistently listen to their prayers from heaven [רש״י, ביאור שטיינזלץ].
Moved by His abundant mercy, God would respond to these cries by sending them capable leaders and saviors, such as Ehud and Deborah. The deliverance these leaders brought was profound. It was not merely a matter of survival or a narrow escape from destruction. Instead, God granted them a complete and absolute victory over those who oppressed them [מלבי״ם].
