They took that which Micah had made, and the priest whom he had, and came to Laish, to a people quiet and secure, and struck them with the edge of the sword; and they burnt the city with fire.
"They ... smote them with the edge of the sword"  (Judges 18:27).  This is a reference to the wholesale slaughter of men, women, children and infants, and the burning of the city with fire might also have been an instrument in the annihilation of the population of that quiet and peaceful little city.
