Judges 18 (résumé): Danites settle in Laish

The Danites were for some reason looking for a new home as they had already received land from Joshua. They sent out 5 men to spy out new options, and when they met Micah's private Levite priest they consulted him as to whether God would bless their mission which he answered positively. The 5 went on to Laish which they found to be prosperous and temptingly vulnerable, so they reported this to their people.

The Danites therefore sent out 600 warriors to conquer Laish and on the way they stole Micah's gods, ephod and carved image. They also took his private Levite priest to be their own tribal priest. Then they attacked Laish and burned down the city renaming it Dan after rebuilding it. They set up their idols, and Gershom, son of Moses and his sons were the priests for their tribe!
