'Copper' in the Bible

And I look, and lo, a tempestuous wind is coming from the north, a great cloud, and fire catching itself, and brightness to it round about, and out of its midst as the colour of copper, out of the midst of the fire.

And I see as the colour of copper, as the appearance of fire within it round about, from the appearance of his loins and upward, and from the appearance of his loins and downward, I have seen as the appearance of fire, and brightness is to it round about.

and I look, and lo, a likeness as the appearance of fire, from the appearance of His loins and downward -- fire, and from His loins and upward, as the appearance of brightness, as the colour of copper.
