Genesis 19:12

Hast thou here any besides? By now Lot must have become aware of the supernatural nature of his visitors. It was time for them to acquaint him with the purpose of their mission, and they proceeded to tell him in the plainest possible language of the impending utter destruction of the city. Although Lot’s married children seem to have adopted the life of the people of Sodom, the angels were willing to save them for Lot’s sake should they be willing to leave the city. Though they shared in the sins of Sodom, nothing but their own choice would render their destruction with it inevitable.
