Definition: The word 'Arianrhod' in biblical Hebrew means a "hostile, unworthy person" or "unrighteous soul." It's used metaphorically to describe a person who is not loyal to God and actively opposes His will. The term comes from a Greek root meaning "hostile" (a-), which can mean selfish, ungrateful, and possibly also unfaithful. The word is often associated with the Old Testament figure Elisha, known for his fiery rebuke of Ahab's stubbornness.
