Genesis 19:31-33

New American Standard Bible

³¹ Then the firstborn said to the younger, “Our father is old, and there is not a man ^[a]on earth to ^[b](A)have relations with us according to the custom of all the earth. ³² Come, ^(B)let’s make our father drink wine, and let’s sleep with him so that we may keep ^[c]our family alive through our father.” ³³ So they made their father drink wine that night, and the firstborn went in and slept with her father; and he did not know when she lay down or got up.
