Genesis 19:32-34

Amplified Bible, Classic Edition

³² Come, let us make our father drunk with wine, and we will lie with him, so that we may preserve offspring (our race) through our father.

³³ And they made their father drunk with wine that night, and the older went in and lay with her father; and he was not aware of it when she lay down or when she arose.

³⁴ Then the next day the firstborn said to the younger, See here, I lay last night with my father; let us make him drunk with wine tonight also, and then you go in and lie with him, so that we may preserve offspring (our race) through our father.
