Genesis 19:30-38 - Lot And His Daughters
30 And Lot goeth up out of Zoar, and dwelleth in the mountain, and his two daughters with him, for he hath been afraid of dwelling in Zoar, and he dwelleth in a cave, he and his two daughters. 31 And the first-born saith unto the younger, 'Our father is old, and a man there is not in the earth to come in unto us, as is the way of all the earth; 32 come, we cause our father to drink wine, and lie with him, and preserve from our father -- a seed.' 33 And they cause their father to drink wine on that night; and the first-born goeth in, and lieth with her father, and he hath not known in her lying down, or in her rising up.
34 And it cometh to pass, on the morrow, that the first-born saith unto the younger, 'Lo, I have lain yesterday-night with my father: we cause him to drink wine also to-night, and go thou in, lie with him, and we preserve from our father -- a seed.' 35 And they cause their father to drink wine on that night also, and the younger riseth and lieth with him, and he hath not known in her lying down, or in her rising up.
36 And the two daughters of Lot conceive from their father, 37 and the first-born beareth a son, and calleth his name Moab; he is father of Moab unto this day; 38 as to the younger, she also hath born a son, and calleth his name Ben-Ammi: he is father of the Beni-Ammon unto this day.
