When he restored the money to his mother, his mother took two hundred [pieces] of silver, and gave them to the founder, who made of it an engraved image and a molten image: and it was in the house of Micah.

They also seem to have been unaware of, or unconcerned about, Israel’s tragic experience with the golden calf at Mt. Sinai (Exodus 32:19-35).
