of copper; a brazen thing a name of contempt given to the serpent Moses had made in the wilderness (Num. 21:8), and which Hezekiah destroyed because the children of Israel began to regard it as an idol and "burn incense to it." The lapse of nearly one thousand years had invested the "brazen serpent" with a mysterious sanctity; and in order to deliver the people from their infatuation, and impress them with the idea of its worthlessness, Hezekiah called it, in contempt, "Nehushtan," a brazen thing, a mere piece of brass (2 Kings 18:4).
They are ancient, and were perhaps used as talismanic copies of nehushtan.
In itself it was only a "nehushtan," but, when used of God, it was a means of rich blessing.
It seems also to have been in some degree connected with that famous relic, the brazen serpent of nehushtan (2 Kings 18, 4).
