Genesis 19:31-33

Darby Translation

³¹ And the first-born said to the younger, Our father is old, and there is not a man in the land to come in to us after the manner of all the earth:

³² come, let us give our father wine to drink, and let us lie with him, that we may preserve seed alive of our father.

³³ And they gave their father wine to drink that night. And the first-born went in, and lay with her father, and he did not know of her lying down, nor of her rising.
