The most common scholarly and philosophical discussions regarding "the rod" stem from the biblical proverb, "He who spares the rod hates his son" (Proverbs 13:24).

In biblical times, a shepherd’s rod was primarily used to guide and protect sheep from danger rather than to strike them. Scholars at The Gospel Coalition argue that the "principle of the rod" is about structure and loving authority, providing children with a sense of right and wrong in a chaotic world.

Historically, the rod was not merely a physical object but a figurative representation of authority and mastery.
