Gen. 19: 31-38
31- And the firstborn
dealt wickedly, and said unto the younger, Our father
has become (is) old, and
we have (there is) not a man
on (in) the earth to come in unto us,
to live with us after the manner
of all that live on the earth:
32-
Therefore come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father.
33- And they
did wickedly, and made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose.
34- And it came to pass on the morrow, that the firstborn said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in,
and lie with him, that we may preserve seed of our father.
35- And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose.
36- Thus were both the daughters of Lot with child by their father.
37- And the firstborn bare a son, and called his name Moab the same
is the father of the Moabites,
the same which are unto this day.
38- And the younger, she also bare a son, and called his name Benammi: (the same is) the father of the children
which are Ammonites, the same which are (of Ammon) unto this day.
