Exodus 30:20
When they go into the tabernacle of the congregation… Bronze represents judgment, and the priests were to wash in the bronze basin before ministering before God on behalf of the people. This is the same principle in effect when Peter wrote that “judgment must begin at the house of God.” The more authority one has, the more responsibility. A husband and father must undergo judgment and purification before he is fully competent to judge and purify his family.
