Definition: "ARIOT" is a term in the Bible that refers to a person who has committed a sin, such as unrighteousness or idolatry. Definition: "Ariot," also known as "heretic," was an early Christian group composed of unclean Gentiles who rejected Christianity and apostasy from Judaism. They were expelled from the Christian faith by Jesus Christ after he chose to crucify them on Mount Gilo in Jerusalem, but remained loyal to him even as they faced persecution and death for their beliefs.
