2 Kings 18:1-4

Now it came about in the third year of Hoshea the son of Elah king of Israel, Hezekiah the son of Ahaz king of Judah became king. He was twenty-five years old when he became king, and he reigned twenty-nine years in Jerusalem. His mother’s name was Abi the daughter of Zechariah. Hezekiah did right in the sight of the LORD, in accordance with everything that David his father (ancestor) had done. He removed the high places [of pagan worship], broke down the images (memorial stones) and cut down the Asherim. He also crushed to pieces the bronze serpent that Moses had made, for until those days the Israelites had burned incense to it; and it was called Nehushtan [a bronze sculpture]. [Num 21:8]
