Judg 9:53

“The homicide Abimelech, bastard son of Gideon, killed the seventy legitimate sons, and, thinking he had hit upon a ruse for securing his grasp on the royal power, he destroyed his accomplices in the crime. He, however, was in turn destroyed by them and in the end was slain with a stone cast by a woman's hand.… In short, countless examples teach us that the profit of human wisdom is illusory, for it is a meager and lowly thing and not a great and preeminent good.”

(Menochius)”
