Genesis 19:33-38

33 So they made their father drink wine in that night, and the elder went in and lay with her father that night, and he knew not when he slept and when he rose up.
34 And it came to pass on the morrow, that the elder said to the younger, Behold, I slept yesternight with our father, let us make him drink wine in this night also, and do thou go in and sleep with him, and let us raise up seed of our father.
35 So they made their father drink wine in that night also, and the younger went in and slept with her father, and he knew not when he slept, nor when he arose.
36 And the two daughters of Lot conceived by their father.
37 And the elder bore a son and called his name Moab, saying, of my father. This is the father of the Moabites to this present day.
38 And the younger also bore a son, and called his name Amman, saying, The son of my family. This is the father of the Ammanites to this present day.
