This image's head [was] of fine (q) gold, his breast and his arms of silver, his belly and his thighs of brass,
(q) By gold, silver, brass, and iron are meant the Chaldean, Persian, Macedonian, and Roman kingdoms, which would successively rule all the world until Christ (who is here called the stone) himself comes, and destroys the last. And this was to assure the Jews that their affliction would not end with the empire of the Chaldeans, but that they should patiently await the coming of the Messiah, who would be at the end of this fourth monarchy.
