Gold It is refined when necessary, reaching 99.9% purity. As well as the element, the God-fearing human being is often "purified" by the "fire", going through trials that make it more resistant and more united to Him.

One more factor gave gold its popularity: the practicality of making objects with it. For being a metal considered "soft", it can be molded, or are made with it quite thin, but resistant films - the foliation, which guarantees the durability to the objects that receive a golden layer.
The more he is subjected to fire, the purer is gold. The more he submits to God, the stronger man is.
