Genesis 19:31–32

And the firstborn 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 from our father.”

One day the older daughter said to the younger, “Our father is old, and there is no man around here to give us children—as is the custom all over the earth. Let’s get our father to drink wine and then sleep with him and preserve our family line through our father.”

Then the firstborn said to the younger, “Our father is old, and there is no man in the land to sleep with us as is the custom of all the land. Come, let’s get our father to drink wine so that we can sleep with him and preserve our father’s line.”

One day the older daughter said to her sister, “There are no men left anywhere in this entire area, so we can’t get married like everyone else. And our father will soon be too old to have children. Come, let’s get him drunk with wine, and then we will have sex with him. That way we will preserve our family line through our father.”

And the firstborn said unto the younger, Our father is old, and there is not a man in the earth to come in unto 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 seed of our father.
