In those days Israel had no king; everyone did as they saw fit

 17:01-13

 In those days Israel had no king; everyone did as they saw fit.

A young Levite from Bethlehem in Judah, who had been living within the clan of Judah, left that town in search of some other place to stay. On his way he came to Micah’s house in the hill country of Ephraim.

Then Micah said to him, “Live with me and be my father and priest, and I’ll give you ten shekels of silver a year, your clothes and your food.” So the Levite agreed to live with him, and the young man became like one of his sons to him. Then Micah installed the Levite, and the young man became his priest and lived in his house. And Micah said, “Now I know that the Lord will be good to me, since this Levite has become my priest.”

This is the closing section that differs from the rest of  Judges. The writer turns from Israel's heroes to two incidents that illustrate the low state of religion and morality in the lawless days when Israel had no central government and everyone 'did as they saw fit.'

This story relates to the time when Philistine pressure on their southern territory led to the mass migration of the Danites to the far north of Isreal. The image set up by Micah was strictly forbidden by the law that the Levites were supposed to administer.

Why?

There is not God in Israelites in that period. everyone did as they saw fit. And there had no king either.

Micah was the thief in his home and they made an idol is against the law. 

A Levite went out and no place to stay means people do not come to the Temple to devote sacrifice to the Lord. The Israelites were lost their spirit and their God.

How?

Do we like these men to do what we saw fit? No, I will follow the command of the Lord.
