And that angel of peace answered me, saying, Wait but a short time, and thou shalt understand, and every secret thing shall be revealed to thee, which the Lord of spirits has decreed. Those mountains which thou hast seen, the mountain of iron, the mountain of copper, the mountain of silver, the mountain of gold, the mountain of fluid metal, and the mountain of lead, all these in the presence of the Elect One shall be like a honeycomb before the fire, and like water descending from above upon these mountains; and shall become debilitated before his feet.

Copper shall be useless; useless also that which neither rusts nor consumes away; and lead shall not be coveted.
