Silver
'Silver' signifies spiritual good or truth from a celestial origin. It also represents the truth of faith, or the truth acquired from self-hood, or proprium. 'Silver' means scientific truth. In Genesis 20:16, it signifies rational truth. 'A piece of silver' signifies a truth, or a knowledge of truth. In the internal sense of the Word, it signifies truth, but also falsity.
