For many years the Philistines held the Hebrews in subjection after their surrender, for they had lost the prestige of faith by which their fathers had gained victory. Yet the mark of their election and the ties of their heritage had not been entirely obliterated by their Creator. But, because they were often puffed up by success, he delivered them for the most part into the power of the enemy, so that with manly dignity they would seek from heaven the remedy of their ills. We submit to God at a time when we are overwhelmed by other reverses; success puffs up the mind. This is proved not only in other matters but especially in that change of fortune by which success returned again from the Philistines to the Hebrews.
[AD 397] Ambrose of Milan on Judges 13:1
