Genesis 19:30-38 - Lot And His Daughters
30 And Lot went up out of Zoar, and dwelt in the mountain and his two daughters with him. for he feared to dwell in Zoar, so he dwelt in a cave, he, and his two daughters. 31 And the firstborn said unto the younger. Our father is old, - and, a man, there is not in the earth to come in unto us, after the way of all the earth. 32 Come on! let us cause our father to drink wine and let us lie with him, that we may keep alive from our father, a seed. 33 So they caused their father to drink wine that night, - and the firstborn went in. and lay with her father, but he noticed not her lying down nor her rising up.
34 And it came to pass on the morrow, that the firstborn said unto the younger, Lo! I lay, last night with my father, let us cause him to drink wine this night also, and go thou in - lie with him, that we may keep alive from our father, a seed. 35 So they caused their father, on that night also to drink wine, and the younger arose, and lay with him, but he noticed not her lying down, nor her rising up.
36 Thus did, the two daughters of Lot conceive from their father. 37 And the firstborn bare a son, and called his name Moab, - the same, is the father of Moab, unto this day. 38 And the younger she also bare a son, and called his name Ben-ammi, - the same, is the father of the sons of Ammon - unto this day.
