Genesis 19:30-32

Darby Translation

³⁰ And Lot went up from Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar. And he dwelt in a cave, he and his two daughters.

³¹ And the first-born said to the younger, Our father is old, and there is not a man in the land to come in to us after the manner of all the earth:

³² come, let us give our father wine to drink, and let us lie with him, that we may preserve seed alive of our father.
