Genesis 19:31 YLT

²⁹  And it cometh to pass, in God's destroying the cities of the circuit, that God remembereth Abraham, and sendeth Lot out of the midst of the overthrow in the overthrowing of the cities in which Lot dwelt.

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.
