Genesis 19:17-19, 30

And it came to pass, when they had brought them forth abroad, that he said, Escape for thy life; look not behind thee, neither stay thou in all the Plain; escape to the mountain, lest thou be consumed. And Lot said unto them, Oh, not so, my lord: behold now, thy servant hath found favor in thy sight, and thou hast magnified thy lovingkindness, which thou hast showed unto me in saving my life; and I cannot escape to the mountain, lest evil overtake me, and I die

And Lot went up out of 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.
