Micah stole 1,100 pieces of silvers from his mother. Micah confessed, and his mother forgave him. Micah returned the silver, but the mother handed a silversmith two hundred pieces of silver in order craft idols for Micah's house. Micah then had his son act as a priest for his idolatrous house.
There was a man of the hill country of Ephraim whose name was Micah. And he said to his mother,The eleven hundred pieces of silver which were taken from you, about which you cursed [the thief] and also spoke about in my hearing, behold, the silver is with me; I took it.And his mother said,Blessed be my son before the Lord.He returned the eleven hundred pieces of silver to his mother, and she said,I had truly dedicated the silver from my hand to the Lord for my son (in his name) to make an image [carved from wood and plated with silver] and a cast image [of solid silver]; so now, I will return it to you.So when he returned the silver to his mother, she took two hundred pieces of silver and gave them to the silversmith who made of it an image [of silver-plated wood] and a cast image [of solid silver]; and they were in the house of Micah. Now the man Micah had a house of gods (shrine), and he made an ephod and teraphim and dedicated and installed one of his sons, who became his [personal] priest. In those days there was no king in Israel; every man did what was right in his own eyes.— Judges 17:1–17:6 (AMP)
The Danites would later take the idols from Micah and set the idols up at the city of Dan (Laish).
