Judges 18:26-29

26 So the Danites went their way, and Micah, seeing that they were too strong for him, turned around and went back home.

27 Then they took what Micah had made, and his priest, and went on to Laish, against a peaceful and unsuspecting people. They attacked them with the sword and burned down their city.

28 There was no one to rescue them because they lived a long way from Sidon and had no relationship with anyone else. The city was in a valley near Beth Rehob.
The Danites rebuilt the city and settled there.

29 They named it Dan after their forefather Dan, who was born to Israel—though the city used to be called Laish.
