      “And Lot went up from Zoar, and stayed in the mountains, and his two daughters with him; for he was afraid to stay in Zoar; and he stayed in a cave, he and his two daughters. Then the first-born said to the younger, “Our father is old, and there is not a man on earth to come in to us after the manner of the earth. “Come, let us make our father drink wine, and let us lie with him, that we may preserve our family through our father.” So they made their father drink wine that night, and the first-born went in and lay with her father; and he did not know when she lay down or when she arose. And it came about on the morrow, that the first-born said to the younger, “Behold, I lay last night with my father; let us make him drink wine tonight also; then you go in and lie with him, that we may preserve our family through our father.” So they made their father drink wine that night also, and the younger arose and lay with him; and he did not know when she lay down or when she arose. Thus both the daughters of Lot were with child by their father. And the first-born bore a son, and called his name Moab; he is the father of the Moabites to this day. And as for the younger, she also bore a son, and called his name Ben-ammi; he is the father of the sons of Ammon to this day” (Ge 19:30–38). So this incestuous relationship gave rise to two tribes that would oppose Israel-The Moabites and the Ammonites.
