(Incest) Lot: Genesis 19:30-36

Now Lot went up out of Zo'ar, and dwelt in the hills with his two daughters, for he was afraid to dwell in Zo'ar; so he dwelt in a cave with his two daughters. And 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 all the earth. Come, let us make our father drink wine, and we will lie with him, that we may preserve offspring through our father." So they made their father drink wine that night; and the first-born went in, and lay with her father; he did not know when she lay down or when she arose. And on the next day, 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 offspring 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. - Genesis 19:30-36
