The names of these twelve princes of the tribes indicated the history of the tribes they represented. The prince of the tribe Reuben was called Elizur, "my God is a rock," referring to the ancestor of this tribe, Reuben, Jacob's son, who sinned, but, owing to his penance, was forgiven by God, who bore his sin as a rock bears the house built upon it. The name of Elizur's father was Shedeur, "cast into the fire," because Reuben was converted to repentance and atonement through Judah, who confessed his sin when his daughter-in-law Tamar was about to be cast into the fire.
