2 Kings 18:2-4

2He was atwenty-five years old when he began to reign, and he reigned twenty-nine years in Jerusalem. His mother’s name was bAbi the daughter of Zechariah. 3 cAnd he did what was right in the eyes of the Lord, according to all that David his father had done. 4 dHe removed the high places and broke the epillars and cut down fthe Asherah. And he broke in pieces gthe bronze serpent that Moses had made, for until those days the people of Israel had made offerings to it (it was called Nehushtan).
 Nehushtan sounds like the Hebrew for both  bronze and  serpent
