After escaping The Destruction Of Sodom, Lot and his two daughters took refuge in a mountain cave (Lot's wife and two sons-in-law did not survive the destruction). One day, Lot's oldest daughter, whose judgment had obviously become severely warped after having lived in Sodom, decided to start an incestuous family -
"Lot and his two daughters left Zoar and settled in the mountains, for he was afraid to stay in Zoar. He and his two daughters lived in a cave. One day the older daughter said to the younger, "Our father is old, and there is no man around here to lie with us, as is the custom all over the earth. Let's get our father to drink wine and then lie with him and preserve our family line through our father." That night they got their father to drink wine, and the older daughter went in and lay with him. He was not aware of it when she lay down or when she got up. The next day the older daughter said to the younger, "Last night I lay with my father. Let's get him to drink wine again tonight, and you go in and lie with him so we can preserve our family line through our father." So they got their father to drink wine that night also, and the younger daughter went and lay with him. Again he was not aware of it when she lay down or when she got up. So both of Lot's daughters became pregnant by their father. The older daughter had a son, and she named him Moab; he is the father of the Moabites of today. The younger daughter also had a son, and she named him Ben-Ammi; he is the father of the Ammonites of today." (Genesis 19:30-38)
Despite their unfortunate beginning, the descendants of Moab became quite numerous and powerful, and were often connected to Bible History (e.g. Numbers 22:3-14, Judges 3:30, 2 Samuel 8:2, Jeremiah 48:11-13). Good and righteous Ruth was a Moabite (Ruth 1:4), and her descendants, through her great-grandson King David (Ruth 4:13-22), formed one of the lines from which Jesus Christ was descended. (Matthew 1:1-17, Luke 3:23-38)
The land of Moab is located east of The Jordan River and The Dead Sea, and south of the Arnon (Numbers 21:10-15). Today, Moab is within the Kingdom of Jordan.
It was in the Plains of Moab, opposite Jericho (Numbers 22:1, 26:63, Joshua 13:32), that the Israelites made their last encampment before they entered the Promised Land after their Wilderness Journey -
"Then Moses climbed Mount Nebo [see Heartbreak Mountain] from the plains of Moab to the top of Pisgah, across from Jericho. There The Lord [see Rock Of Ages] showed him the whole land - from Gilead to Dan, all of Naphtali, the territory of Ephraim and Manasseh, all the land of Judah as far as the western sea, the Negev and the whole region from the Valley of Jericho, the City of Palms, as far as Zoar. Then The Lord said to him, "This is the land I promised on oath to Abraham, Isaac and Jacob when I said, 'I will give it to your descendants.' I have let you see it with your eyes, but you will not cross over into it." And Moses the servant of The Lord died there in Moab, as The Lord had said. He buried him in Moab, in the valley opposite Beth Peor, but to this day no one knows where his grave is. Moses was a hundred and twenty years old when he died, yet his eyes were not weak nor his strength gone. The Israelites grieved for Moses in the plains of Moab thirty days, until the time of weeping and mourning was over." (Deuteronomy 34:1-8)
