Definition & Meaning of "an army of sheep led by a lion would defeat an army of lions led by a sheep"

What is the origin of the proverb "an army of sheep led by a lion would defeat an army of lions led by a sheep" and when to use it?

The proverb "an army of sheep led by a lion would defeat an army of lions led by a sheep" is often mistakenly attributed to various ancient sources, including Alexander the Great. However, it does not have a confirmed, widely accepted origin in classical texts. This saying suggests that leadership qualities, such as courage, intelligence, and the ability to inspire, are far more crucial to success than mere strength or numbers. The proverb serves as a reminder that leadership can be the deciding factor in overcoming challenges, regardless of the initial resources or power available.
