This noun appears in Proverbs 9:13, where 'the woman Folly' is personified in deliberate contrast to Lady Wisdom earlier in the chapter. While Wisdom calls out from the high places of the city offering life and understanding, the woman Folly also calls out, but her house is the way to death. The personification makes folly not just an abstract concept but an active, seductive force competing for human allegiance. The term emphasizes intellectual and moral stupidity, the opposite of the wisdom that Proverbs celebrates throughout.
