And they took the things which Micah had made, and the priest which he had, and came unto Laish, unto a people that were at quiet and secure: and they smote them with the edge of the sword, and burnt the city with fire. (Judges 18:27)
The report given by the spies was accurate. The heartless Danites surprised the people of Laish, who were unprepared for resistance. The city was captured and burned to the ground.
