Genesis 19:17-19, 30

So it came to pass, when they had brought them outside, that he said, “Escape for your life! Do not look behind you nor stay anywhere in the plain. Escape to the mountains, lest you be destroyed.” Then Lot said to them, “Please, no, my lords! Indeed now, your servant has found favor in your sight, and you have increased your mercy which you have shown me by saving my life; but I cannot escape to the mountains, lest some evil overtake me and I die.

Then Lot went up out of Zoar and dwelt in the mountains, and his two daughters were with him; for he was afraid to dwell in Zoar. And he and his two daughters dwelt in a cave.
