Israel's history is a cycle: they cry out to God in distress, He rescues them, and then they forget His mighty deeds. This verse highlights that pattern.
The Cycle of Sin and Salvation
The book of Judges chronicles a painful cycle in Israel's history. When they were oppressed and in dire straits, they would cry out to God for help. In His mercy, God would raise up judges to deliver them from their oppressors.
But time and again, after deliverance, Israel would fall back into idolatry and disobedience, forgetting the God who had saved them. The Lord's question here in Judges 10:11 is a rhetorical reminder of His faithfulness, contrasting it with Israel's persistent unfaithfulness.
He lists specific instances of His powerful intervention: saving them from Egypt, defeating the Amorites, and rescuing them from the Ammonites and Philistines. This wasn't a history lesson; it was a pointed accusation against their current state of backsliding.
