Genesis 19:29-32 The Message (MSG)
29 And that’s the story: When God destroyed the Cities of the Plain, he was mindful of Abraham and first got Lot out of there before he blasted those cities off the face of the Earth.
30 Lot left Zoar and went into the mountains to live with his two daughters; he was afraid to stay in Zoar. He lived in a cave with his daughters.
31-32 One day the older daughter said to the younger, “Our father is getting old and there’s not a man left in the country by whom we can get pregnant. Let’s get our father drunk with wine and lie with him. We’ll get children through our father—it’s our only chance to keep our family alive.”
