And when the morning arose, then the angels hastened Lot, saying, Arise, take 
thy wife, and thy two daughters, which are here; lest thou be consumed in the 
iniquity of the city. And while he lingered, the men laid hold upon his hand, and upon the hand of his 
wife, and upon the hand of his two daughters; the LORD being merciful unto him: 
and they brought him forth, and set him without the city. 
Genesis 19:15,16
