Moses father in law Exodus gives three names for Moses' father in law. One is "the priest of Midian", one is "Reuel" and the other is "Jethro". From Strongs Dictionary: The way I understand it is that the names give a higher meaning to his relationship to the tribes of Israel ( priest from the tribes of Israel), his relationship to God (Freind of God) and His relationship to man (his excellence) as he was highly respected amongst men because of the first two names. Some explanations say that Reuel was the father of Jethro, but how could they both have the same title as the priest of Midian? In Numbers and Chronicles the bible states who the sons of Reuel where but never mentions Jethro?
