What is "Lo Shav Ad ha'Makehu"?
1.

2.
Radak: They did not contemplate that Hashem strikes them for their sins, and repent.
3.
Malbim: They constantly return to ask for help from the nations that strike them. Really, the nations are merely a staff in Hashem's hand. Why don't they turn to the One who truly strikes them?
