Silver, gold, and copper represent three types of Jews: Silver represents those among us who are not fazed by the spiritual darkness of the mundane world but who, on the contrary, channel Divine consciousness into it. Gold represents those of us who used to be entrenched in the mundane world, but have overcome the stranglehold of its materialism. Copper represents those of us who are still struggling to overcome the materialism of the mundane world.
The Torah requires that all three metals be used for the construction of the Tabernacle. This is a lesson both for those who perceive themselves as gold and silver as well as to those who think of themselves as copper. The “silver” among us must not shy away from involvement in the physical world, preferring instead to occupy themselves with only spiritual matters. Similarly, the “gold” among us, who overcame materialism and therefore might feel immune to its dangers, are still not exempt from elevating the physical world. Finally, the “copper” among us might think that they first have to refine themselves before they can elevate the world, but the Torah tells them otherwise: they, too, must do their part in building G‑d’s home in this world.1

Good Morning,
Dynamic words of wisdom! Just like a coal miner, a "gem miner" risk his life to find hidden treasures. Deeply he descends into the darkness of the earth searching with only a small light on his helmet, a tool in his hand, a carrier on his back to put his findings. He labors for hours, days, weeks, years. The labor is mundane. The findings are small. Then one day, he finds gold! He knew that he would! Joyously, he keeps digging and digging. He finds diamonds, rubies, emeralds, amethysts, topazs, sapphires! Now, he has made enough money to buy the mine and the field. He is rich and so is his family and his friends. That's the "words" of Torah! The "gold mine" never stops giving and blessing. But you have to keep digging and never tire. Always stay in awe of the "Words" of GD!
