Genesis 19:32-35 ▼

32 Come, let us get our father drunk with wine so we can sleep with him and preserve his line.”

33 So that night they got their father drunk with wine, and the firstborn went in and slept with her father; he was not aware when she lay down or when she got up.

34 The next day the older daughter said to the younger, “Look, I slept with my father last night. Let us get him drunk with wine again tonight so you can go in and sleep with him and we can preserve our father’s line.”

35 So again that night they got their father drunk with wine, and the younger daughter went in and slept with him; he was not aware when she lay down or when she got up.
