Judges 17:4, 5
So he returned the silver to his mother, and she took two hundred shekels of silver and gave them to a silversmith, who made them into a graven image and a molten idol. And they were placed in the house of Micah. / Now this man Micah had a shrine, and he made an ephod and some household idols, and ordained one of his sons as his priest.
