Twelve Stones (twelve מצבות (matzevot) or staning stones) was a common form of marking a spectacular religious event in the times of biblical Israel before the time of King Josiah. The stones were specifically placed in a circle in the place where the heads of each tribe stood at the meeting that the 12 tribes had with Joshua as their leader immediately following the crossing of the Jordan River into their homeland. This was practiced for a limited period of time in the Northern kingdom of Israel. It appears to be based upon the prophet Elijah having used using twelve stones to build an altar. The stones were from a broken altar that had been built on Mount Carmel before the First Temple was erected. Upon the completion of the Temple, offerings on other altars became forbidden. What was unique with Elijah's altar was that God would ignite the offering with fire (or lightning) from heaven. The timing of this display made it the most spectacular religious event since the Exodus from Egypt. Hence, use of Twelve Stones became a form of marking a spectacular event. King Josiah abolished the practice because some people attached religious significance to the stones themselves, resembling idolatry.
