Judges 18:27-29

27But the people of Dan took what Micah had made, and the priest who belonged to him, and they came to Laish, to a people quiet and unsuspecting, and struck them with the edge of the sword and burned the city with fire.

28And there was no deliverer because it was far from Sidon, and they had no dealings with anyone. It was in the valley that belongs to Beth-rehob. Then they rebuilt the city and lived in it.

29And they named the city Dan, after the name of Dan their ancestor, who was born to Israel; but the name of the city was Laish at the first.
