Targum for Genesis 19:30

וַיַּעַל֩ ל֨וֹט מִצּ֜וֹעַר וַיֵּ֣שֶׁב בָּהָ֗ר וּשְׁתֵּ֤י בְנֹתָיו֙ עִמּ֔וֹ כִּ֥י יָרֵ֖א לָשֶׁ֣בֶת בְּצ֑וֹעַר וַיֵּ֙שֶׁב֙ בַּמְּעָרָ֔ה ה֖וּא וּשְׁתֵּ֥י בְנֹתָֽיו׃

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.
