Judges 18:23
And they cried unto the children of Dan. And they turned their faces, and said unto Micah, What aileth thee, that thou comest with such a company? And they cried unto the children of Dan. And they turned their faces, and said unto Micah, What aileth thee, that thou comest with such a company?
Chapters 17-21 belong to the early part of the period of the judges and are placed out of chronological order, since the main story of the book ends with chapter 16. In its immediate setting the Danites were on a journey to seize Micah's images and take his Levite priest to serve their tribe. When Micah pursued them with a company they turned their faces and challenged him with the question what ailed him, marking their forceful removal of the objects and priest from his household. That same expedition carried Micah's priest and idols to Laish, where the Danites destroyed the city, renamed it Dan, and established idolatrous worship there.
That worship at Dan continued until the captivity of the ten tribes, and its long standing made it easier for Jeroboam later to set up a golden calf at Dan and draw the people into its worship. The verse belongs to an account of disorder prevailing in Israel when people did what seemed right to them, and the events of chapters 18 and 19 show how far society had fallen into immorality. It is part of a record of Israel's backsliding and its resulting disgrace and punishment, showing that no one can backslide without punishment. The apostasy of Dan described in this chapter is a possible but not definite reason why the tribe of Dan was omitted from the list of tribes sealed in Revelation 7:1-8.
