Judges 17:4-6

So after he returned the silver to his mother, she took two hundred shekels of silver and gave them to a silversmith, who used them to make the idol. And it was put in Micah’s house. Now this man Micah had a shrine, and he made an ephod and some household gods and installed one of his sons as his priest. In those days Israel had no king; everyone did as they saw fit.
