Today, I invite you to read Judges 18.  The tribe of Dan had failed to take possession of its land when the Israelites were led into the promised land by Joshua.  Now, years later, they seek to recover what they had never possessed because of their rebellion against God.  First, they send spies into the territory, who don't seek God, but devise a scheme to take advantage of people who are living peacefully.  These spies bring a large contingent of armed men and first take advantage of Micah's hospitality by stealing his idols and his "personal" priest.  The pursuit of idolatry continues and flourishes in the Northern Kingdom.  These are the seeds of full blown idolatry which we witness later at the time of Israel's exile.  Without the Lord's blessing, they also destroy the city of those who live in the region, again seeking to manipulate God in their own strength.  While they were filled with confidence, their actions are very foolish.  Filled with arrogance and pride, they reject God and His ways.
