'Burnished' in the Bible

And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot; and they sparkled as the look of burnished brass.

and his body was like a chrysolite, and his face as the appearance of lightning, and his eyes as torches of fire, and his arms and his feet as the look of burnished brass, and the voice of his words like the voice of a multitude.
