Judges 18 describes members of the tribe of Dan searching for territory and discovering the prosperous city of Laish. They captured the city, destroyed it, rebuilt it, and named it Dan.
The Danites established a sanctuary there, and the account describes an image and priesthood that continued for an extended period.
After the kingdom divided, Jeroboam I established golden calves at Bethel and Dan to provide alternative royal sanctuaries to Jerusalem.
Dan subsequently became the northern endpoint in the familiar biblical expression "from Dan to Beersheba."
