Genesis 19:30
Lot and His Daughters
30 Now Lot went up out of Zoar and mlived in the hills with his two daughters, for he was afraid to live in Zoar. So he lived in a cave with his two daughters.
Genesis 19:35–37
35 So they made their father drink wine that night also. And the younger arose and lay with him, and he did not know when she lay down or when she arose. 36 Thus both the daughters of Lot became pregnant by their father. 37 The firstborn bore a son and called his name Moab.1 nHe is the father of the Moabites to this day.
