"The Moabites dwelt on the East side of the Dead Sea, and they were a constant thorn in Israel's side throughout Old Testament history. Their original ancestor was Moab who was actually the child of Lot and his daughter who committed incest with him because she thought it was the end of the world after having been in the area when Sodom and Gomorrah were destroyed by fire and brimstone from heaven. One famous Moabite mentioned in the Bible was Ruth who is mentioned in the genealogy of Jesus Christ in Matthew 1."
