Genesis 19:30-38 - Lot And His Daughters
30 And Lot departed out of Zoar and dwelled in the mountains and his two daughters with him for he feared to tarry in Zoar: he dwelt therefore in a cave, both he and his two daughters also. 31 Then said the elder unto the younger, "Our father is old, and there are no more men in the earth to come in unto us after the manner of all the world. 32 Come therefore, let us give our father wine to drink, and let us lie with him that we may save seed of our father." 33 And they gave their father wine to drink that same night. And the elder daughter went and lay with her father. And he perceived it not; neither when she lay down, neither when she rose up.
34 And on the morrow the elder said unto the younger, "Behold, yesternight lay I with my father. Let us give him wine to drink this night also, and go thou and lie with him, and let us save seed of our father." 35 And they gave their father wine to drink that night also. And the younger arose and lay with him. And he perceived it not; neither when she lay down, neither when she rose up.
36 Thus were both the daughters of Lot with child by their father. 37 And the elder bare a son and called him Moab, which is the father of the Moabites unto this day. 38 And the younger bare a son and called him Benammi, which is the father of the children of Ammon unto this day.
