"Now it came to pass in the days when the judges ruled, that there was a famine in the land. And a certain man of Bethlehemjudah went to sojourn in the country of Moab, he, and his wife, and his two sons." These are important words, and upon these words hangs the whole truth of who Ruth was. When we understand the journeying of Israel into the Promised Land, the route they took, and the battles they fought on the way, and the land they conquered, annihilating the former holders of that land, the whole truth of the matter of Ruth's identity is revealed.
It is only left for me to pass you on to Chaazawan who, after a great deal of prayer, study and illumination from his studies, comes up with the truth. Enjoy! Ruth the Israelite
