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.

Arcana Coelestia #158
158. That 'man' (vir) means the internal man, or what amounts to the same, one who is intelligent and wise, is clear in Isaiah,
I look, and there is no man, and from these there is no counsellor. Isaiah 41:18.
['No man'] stands for no wise and intelligent person. In Jeremiah,
Run to and fro through the streets of Jerusalem and see if you find a man, if anyone is executing judgement and seeking truth. Jeremiah 5:1.
'Executing judgement' stands for being wise, and 'seeking truth' for having intelligence.
