"And he shall sit refining and cleansing the silver, and he
shall purify the sons of Levi and shall refine them as gold
This verse puzzled some women in a Bible study and they wondered what this statement meant about the character and nature of God. One of the women offered to find out the process of refining silver and get back to the group at their next Bible Study. That week, the woman called a silversmith and made an appointment to watch him at work. She didn't mention anything about the reason for her interest beyond her curiosity about the process of refining silver. As she watched the silversmith, he held a piece of silver over the fire and let it heat up. He explained that in refining silver, one needed to hold the silver in the middle of the fire where the flames were hottest as to burn away all the impurities.
